Question

the circumference of a circle is 11pi inches. what is the area, in square inches, of the circle? express in terms of pi.

Answer 1

`2 \pi r=circumference of the circle r=5.5 (5.5) x^(2) \pi =area 30.25 \pi =area`

30.25
`\pi` square inches is the area for the circle

Answer 2

C= pi d
therefore 11= diameter
radius is 1/2 the diameter
radius= 5.5

A= pi r^2
A=30.25 pi
hope this helps
