Question

A circular piece of fabric has a radius of 1.2 feet.
The fabric sells for $5.40 per square foot.

What is the total cost of the circular piece of fabric?

A.
$6.48

B.
$20.35

C.
$24.42

D.
$40.69

Answer 1

First find the area of the circle.

A = pi * r^2.
A = pi * 1.2^2
A = 4.52389342117ft^2

Now multiply that by the price of 5.40 / sqft.

4.52389342117 * 5.40 = 24.42$
