Answer:
16π cm²
Step-by-step explanation:
circumference = 2πr
Area = πr²
We need to determine r to calculate the area
2πr = 8π
Divide both sides of the equation by 2π to find r
r = 4
Now, we determine area.
area = πr² = π4² = 16πcm²
4/7 can be equivalent to 8/14 (Multiplied top and bottom of fraction by 2)
It can also be equivalent to 12/21. (Multiplied by 3)
16/28.
And so on.
