A circle has diameter of 18 feet what the area

Answer: 254.34

Step-by-step 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

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
