Best ResponseYou've already chosen the best response.0Yeah 105 is correct answer.

Best ResponseYou've already chosen the best response.0thanks and um that would be cm

geerky42

Best ResponseYou've already chosen the best response.0No. \(\text{cm}\times\text{cm} = \text{cm}^2\), right?

geerky42

Best ResponseYou've already chosen the best response.0Since you did \(7~\text{cm}\times 15~\text{cm}\)

anonymous

Best ResponseYou've already chosen the best response.0oh yes i forgot sorry

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0okay, so answer is \(105~\text{cm}^2\)

anonymous

Best ResponseYou've already chosen the best response.0ok so @geerky42 is this right

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0You did \(\dfrac{1}{2} (8~\text{cm}\times10~\text{cm}) \)

Best ResponseYou've already chosen the best response.0You can treat units like variable

geerky42

Best ResponseYou've already chosen the best response.0\(\text{cm}\times\text{cm} = \text{cm}^2\) Just like how \(x\times x = x^2\)

anonymous

Best ResponseYou've already chosen the best response.0ah ok that makes more sense

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0Area should be \(3.14~\text{yd}^2\)

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0Because you have \(\pi r^2\) So you squared unit too.

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0\[\pi r^2~~~\rightarrow~~~\pi(1~\text{yd})^2\]

geerky42

Best ResponseYou've already chosen the best response.0Yeah. What about circumference?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok and my circumference is 6.28yd2

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0\[2\pi r ~~~\rightarrow~~~2\pi(1~\text{yd})\]

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0that "2" has no unit.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ah ok so circumference is usually 1pi

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0\[C = 2\pi (1~\text{yd})\]

anonymous

Best ResponseYou've already chosen the best response.0yeah that's the formula i used

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0im not sure what to do here

Best ResponseYou've already chosen the best response.0It's basically semicircle subtract triangle

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0if the radius is 6 that means the diameter is 12

anonymous

Best ResponseYou've already chosen the best response.0huh? so how do I start to solve

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0find area of triangle and area of semicircle, then you do semicircle  triangle

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0wait but only the height is given for the triangle how would i find the base

geerky42

Best ResponseYou've already chosen the best response.0dw:1433376534008:dw

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0So base (aka diameter) is 12 yd.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok i got that because diameter is twice as much as radius

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0yeah. Do you understand how I got base.

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0no how is the diameter the base

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0Try imagine rotating height into base, then you will see that height is half the base.

Best ResponseYou've already chosen the best response.0dw:1433377025268:dw

geerky42

Best ResponseYou've already chosen the best response.0Height is also radius.

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0Still don't understand?

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0so what is my next step

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0"find area of triangle and area of semicircle, then you do semicircle  triangle"

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0ok so then i have 36 for the triangle and 56.52

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0thanks that wasn't hard

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0hey do you know about midpoint

anonymous
 one year ago
Best ResponseYou've already chosen the best response.0i would do x1+x2/2 y1+y2/2 right

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0\[\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)\]

anonymous

Best ResponseYou've already chosen the best response.0ok i think i got this wring

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0\[\left(\dfrac{6+2}{2},\dfrac{8+4}{2}\right)\]

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0\[\left(\dfrac{8}{2},\dfrac{12}{2}\right)\]

geerky42
 one year ago
Best ResponseYou've already chosen the best response.0yeah, so 8 divide by 2 is 4.

Best ResponseYou've already chosen the best response.0what about this @geerky42
