Question

How do I find the area of a circle when the circumference is 58 pie

Answer 1

C=2$\pi$r
A=$\pi$r²

C=2$\pi$r=58$\pi$
2r=58
r=29

A=$\pi$r²
A=29²$\pi$
A=841$\pi$

Answer 2

C=πd
58π=πd
We conclude that
d=58 cm
r=1/2d
r=58(1/2)
r=29 cm
A=πr^2
A=29^2π
A=841π
Or
A≈2640.74 square cm. Hope it help!
