we need question 2 part b
OpenStudy (igreen):
So..you don't need Part A?
OpenStudy (mvpriest6):
no we have a circle that is 8 inches diameter thats the info we need from part a
OpenStudy (mvpriest6):
figure out part b now i already know part a
OpenStudy (igreen):
The formula for the area of a circle is:
\(\sf A = \pi r^2\)
It says the picture's diameter is 8 inches. The diameter of the picture and the frame is 10 inches, because the frame adds on 2 inches.
\(\sf A = \pi \times 10^2\)
Can you solve that?

@iGreen u there
OpenStudy (igreen):
Oops it said the diameter was 8 inches..adding 2 will make it 10 inches..and the radius is half the diameter. Half of 10 is 5, so the radius is 5..so we actually have:
\(\sf A = \pi r^2\)
\(\sf A = 5^2 \pi\)
\(\sf 5^2 \rightarrow 5 \times 5 \rightarrow~?\)
OpenStudy (mvpriest6):
@AnswerMyQuestions could you help

Made another mistake..actually the radius would be 12..and half of that is 6..so what's \(6 \times 6\)?
OpenStudy (igreen):
That will be your answer.
OpenStudy (mvpriest6):
