You can put this solution on YOUR website!
If the bucket's edge has a circumference of 7 cm, we can find its radius by
C=2%28pi%29r
7=2%28pi%29r
and solving for r, we get
r+=+7%2F%282%28pi%29%29
The area if found by
A+=+%28pi%29%2Ar%5E2
A+=+%28pi%29%2A%287%2F%282%28pi%29%29%29%5E2
A+=+49%2F4%28pi%29 square cm
