Question

A circle has diameter of 18 feet what the area

Answer 1

d= 18 feet, so r = d/2= 18/2=9 feet

A= πr^2

A= 3.14 x 9x 9

A= 254.34 square feet

Answer 2

Answer: 254.34

Explanation:

The area of a circle is calculated by the formula A=π r²

A = Area

r² = radius squared

Putting the numbers into the formula:

A = 3.14 x 9²

A = 3.14 x 81

A = 254.34
