HELP!! Suppose the area of a circle is 201.0624 square feet. What's the diameter of the circle? (Use π = 3.1416.)
1 answer:
<u>Answer</u>
C. 16 feet
<u>Explanation</u>
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
