Find the area of the circle. Use 3.14 for pie the diameter is 9 Round your answer to the nearest hundredth, if necessary.

Answer 1

The radius of the circle is half the diameter, so:

r = 9/2 = 4.5

The formula for the area of a circle is:

A = πr^2

Plugging in the values we have:

A = 3.14 x 4.5^2
A = 3.14 x 20.25
A = 63.585

Rounding to the nearest hundredth, the area of the circle is:

A = 63.59 (rounded to two decimal places)
