Think about it. Whats the formula for circumference?

\[circumference = 2 \pi r\]find r
then \[area = \pi r^2\]

for finding area we need value of radius ....
circumference = 2πr
Area = πr^2

31.4CM =2πr
r = 4.99

Get it? Cuz 31.4CM divided by 2 divided by π gives you r

Round that number to 5.

Now plug the new radius into the area formula

πr2

π5^2

= 78.5cm3

pottersheep has just established that:\[\text{area of a circle}=\frac{c^2}{4 \pi }\]
