Question

HELP!! Suppose the area of a circle is 201.0624 square feet. What's the diameter of the circle? (Use π = 3.1416.)

Answer 1

Answer

C. 16 feet

Explanation

The area of a circle is given by the formula:

Area = πr² Where r is the radius of the circle and π = 3.1416

201.0624 = 3.1416 × r²

r² = 201.0624/3.1416

    = 64

r = √64

   = 8 feet

Diameter is twice the radius.

∴ diameter = 2r

                  = 2 × 8

                  = 16 feet
