Question

C. A wheel barrel tire has circumference of 31.42 inches, find the area of the tire

Answer 1

Area: 25π ≅ 78.54

Explanation:

Area of a circle: A = πr^2

A = Area

π = PI

R = Radius

Circumference: C = 2πr

So if circumference = 31.42

31.42/2π = 2πr/2π

5 = r

Now, A = π(5)^2

A = 25π
