Answer 1

С=8пи=2пиR
R=8пи/2пи
R =4
S=пиR^2
S= пи×4^2=16пи

Answer 2

Calculating the Area of a Circle

To calculate the area of a circle when the circumference is given, we can use the formula:

Area = (Circumference)^2 / (4 * π)

Where: - Circumference is the length around the circle - π (pi) is a mathematical constant approximately equal to 3.14159

Calculation

Given that the circumference of the circle is 8π, we can calculate the area using the formula:

Area = (8π)^2 / (4 * π)

Result

The area of the circle, bounded by the given circumference, is 16π square units.

This calculation is based on the formula for the area of a circle derived from the given circumference
