Answer:
A = 156.25π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
• A = πr² ( r is the radius )
We require to find radius r
The circumference (C) of a circle is calculated as
• C = 2πr
given C = 25π , then
2πr = 25π ( divide both sides by 2π )
r = [tex]\frac{25\pi }{2\pi }[/tex] = 12.5
Then
A = π × 12.5² = 156.25π cm²
