Best ResponseYou've already chosen the best response.0find the surface area of the solids. the pyramids are regular and the prisms, cylinders, and cones are right

Best ResponseYou've already chosen the best response.0For the first one, you can find the surface area of the cylinder part ( the part that looks like a can) by using 2(pi)r * height

Best ResponseYou've already chosen the best response.0Then add the area of the bottom circle (pi)r^2

Best ResponseYou've already chosen the best response.0and then add SA of the cone, pi*r*s s is the slant height

Best ResponseYou've already chosen the best response.0thats what i did and i got 211.95cmin^2

Best ResponseYou've already chosen the best response.0ok, let me try and work it out with the numbers, just a sec

Best ResponseYou've already chosen the best response.0wekkm 203.58 cm^2 when I use the pi button

Best ResponseYou've already chosen the best response.0for the cylinder, it's 30.6pi, the circle base is 9pi, and the cone is 25.2pi

anonymous

Best ResponseYou've already chosen the best response.0so it would be 30.6pi+9pi+25.2pi

anonymous

Best ResponseYou've already chosen the best response.0yes, and with that I got 64.8pi

Best ResponseYou've already chosen the best response.0For the 2nd picture, there are 6 sides that are rectangles, so that would be 6(base*height). I can't tell in the picture, is the height of each triangle 5, or what does the 5 go to?

anonymous

Best ResponseYou've already chosen the best response.0to the slant eight of the triangle

anonymous

Best ResponseYou've already chosen the best response.06 there are 6 triangles, each with a base of 3 and slant height of 5.....that would be 6 * 1/2 (base * height)

anonymous

Best ResponseYou've already chosen the best response.0So, 6(3*6) +6(1/2)(3*5)

anonymous

Best ResponseYou've already chosen the best response.0and then would you have to add the area of the base?

anonymous

Best ResponseYou've already chosen the best response.0where did you get 855?

anonymous

Best ResponseYou've already chosen the best response.06(3*12) +6(1/2)(3*5) that would be a 12 in the first ( )

Best ResponseYou've already chosen the best response.064.8pi went to the first drawing...the one above is for the 2nd picture

anonymous

Best ResponseYou've already chosen the best response.0i thought the first pic was 203.58cm^2

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yes, that's what I got....it was 64.8pi, which = 203.58cm^2

anonymous

Best ResponseYou've already chosen the best response.0for the 2nd drawing I get 261in^2 + area of that hexagon base

anonymous

Best ResponseYou've already chosen the best response.0261 in^2 so this is the second pic surface area?

anonymous

Best ResponseYou've already chosen the best response.0yes, but I dont' know how to find area of the base

Best ResponseYou've already chosen the best response.0will u help me with some other ones that ive already done i just got them wrong

anonymous

Best ResponseYou've already chosen the best response.0okay.. for this one i needed to find the value of x.. and i got 3

anonymous

Best ResponseYou've already chosen the best response.0so redoing it i get \[56.5=1/3\times \pi \times x ^{2}\times6\]

Best ResponseYou've already chosen the best response.0Did it count off because you didn't put meters?

anonymous

Best ResponseYou've already chosen the best response.0oh, wait, is x the diameter? We only found the radius.

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0yeah, then sq rt of that gives the radius of that circle as 3 meters

anonymous
 5 years ago
Best ResponseYou've already chosen the best response.0but in the drawing, the x represents the diameter, which would be twice the radius, or 6 meters

anonymous

Best ResponseYou've already chosen the best response.0I've got to go....good luck!
