Answer:

a. Area of circle = 50.24 ft².

b. Circumference of circle = 25.12 ft.  

Step-by-step explanation:

Given the following data;

Diameter = 8ft

Pie, π = 3.14

Radius, r = diameter/2 = 8/2 = 4ft

a. To find the area of the circle;

Area of circle = πr²

Substituting into the equation, we have;

Area of circle = 3.14*(4)²

Area of circle = 3.14*16

<em>Area of circle = 50.24 ft²</em>

b. To find the circumference of the circle;

Circumference of a circle = 2πr

Substituting into the equation, we have;

Circumference of circle = 2*3.14*4

<em>Circumference of circle = 25.12 ft. </em>
