Question

Find the circumference of the circle and area of the circle.

Answer 1

C = 50.24

A = 7,925.540864 (Round to whatever you want)

Explanation:

c = 2πr

c = 2(3.14)(8)

c= 50.24

A = πr^2

A = (3.14)(50.24)^2

A = 7,925.540864

Answer 2

Answer: circumference = 50.24

Area = 200.96

Explanation:

The circumference of a circle is same as its perimeter.

The formula for determining the perimeter of a circle is expressed as

Perimeter = 2πr

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

From the diagram

r = 8

Therefore,

Circumference = 2 × 3.14 × 8 = 50.24

The formula for determining the area of a circle is

Area = πr²

Area = 3.14 × 8² = 200.96
