None of these answer choices are correct. Is there something missing from one of them?
anonymous
  • anonymous
ohhh they are missing the ^2

on which ones?
anonymous

all of them
anonymous

is (10in)^2 on all of them
jim_thompson5910
  • jim_thompson5910
how is the ^2 written? over the 37?
jim_thompson5910
  • jim_thompson5910
oh ok
jim_thompson5910

what is the area of the entire circle? use this formula A = pi*r^2
anonymous
  • anonymous
985.96?
jim_thompson5910
  • jim_thompson5910
if r = 10, then r^2 = ??

ohh wait my math was wrong. i didnt follow pemdas

314 (putting pi as 3.14)
jim_thompson5910
  • jim_thompson5910
don't replace pi with 3.14, leave pi as it is
anonymous
  • anonymous
ahhhh ok hold on
anonymous
  • anonymous
314.159..
jim_thompson5910
  • jim_thompson5910
no it would just be 100pi
jim_thompson5910
  • jim_thompson5910
think of pi as a variable
anonymous
  • anonymous
oh ok
jim_thompson5910
  • jim_thompson5910
now apparently, they didn't square the 10 to get 100 they left it as 10^2 so we'll have (10)^2*pi as part of the answer
jim_thompson5910
  • jim_thompson5910
or pi*(10)^2
jim_thompson5910
  • jim_thompson5910
`pi*(10)^2` is the area of the WHOLE circle we just want that pizza slice to get the area of that slice, we multiply by 37/360
jim_thompson5910
  • jim_thompson5910
\[\Large \pi*(10)^2\times\frac{37}{360} = \frac{\pi\times(10)^2\times37}{360}\]
jim_thompson5910
  • jim_thompson5910
example: say the angle is 90 degrees 90/360 = 1/4 so we take a quarter of the full area to get the slice area
anonymous
  • anonymous
ahh.. so the answer is b?
anonymous
  • anonymous
nooo its a. the things were written wrong. i see
anonymous
  • anonymous
a) π(10in)^2 37 over 360 b) π(10in) 37 over 360 c) π(37in)^2 10 over 360 d) π(37in) 10 over 360
jim_thompson5910
  • jim_thompson5910
ah I see now, thanks
jim_thompson5910
  • jim_thompson5910
yeah it's definitely A
anonymous
  • anonymous
yay thank you!!
jim_thompson5910
  • jim_thompson5910
no problem
