Question

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

A. 64 feet
B. 8 feet
C. 16 feet
D. 64 square feet

Answer 1

C. 16 feet

Step-by-step 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
