Hello!

ANSWERS:

The area of the circle is 200.98 ft^2.

The circumference of the circle is 50.24 feet.
_____________________________

EXPLANATION:

We must use formulas to find the area and circumference of a circle.

A = pi × r^2

C = 2 × pi × r

-------------------------------------------------------

We know that pi equals approximately 3.14 and the radius of the circle is 8 feet. That is all we'll need to find the area and circumference of the circle.

-------------------------------------------------------

AREA:

A = pi × r^2

A = 3.14 × 8^2

A = 3.14 × 64

A = 200.98 feet^2

_____________________________

CIRCUMFERENCE:

C = 2 × pi × r

C = 2 × 3.14 × 8

C = 6.28 × 8

C = 50.24 feet
