Question

Using the illustration below, calculate the area of the circle.

Answer 1

R=14.5
r=R/2
r=14.5/2
r=7.25
A= r^2π
A= 7.25^2π
A=165.04625

Answer 2

Find thy radius.

Thy radius is 7.25 (D / 2 = R)

Thy formula for area is A = (pi)r^2

Substitute and Solve

A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625

Therefore, the area is about 165.
