Question

Find the area and the circumference of a circle with diameter 8 ft.

Answer 1

Area: pir^2

r=4

4pi^2

if pi=3.14

then the area is 50.24ft^2

Circumference: pi x d

d=8

8pi

if pi=3.14

then the circumference is 25.12ft.

Answer 2

Circumference=8πft

Area=16π ft²

Step-by-step explanation

The circumference of a circle calculated using the formula:

C=πd

The diameter of the circle is 8ft.

The circumference is

C=8π ft.

The area of a circle is given by:

A = πr²

Where r=8/2=4 ft is the radius of the circle.

Therefore the area is

A = π×4²

A=16π ft²
