Find the area to this problem

254.34 in²

Step-by-step explanation:

Given:

Diameter of the circle = 18 in

To find:

Area of the circle

Solution:

Let the area be a.

First, we find the radius of the circle by dividing the diameter by 2.

This comes out to be 9 in.

Now, we apply the formula

Solving, we get

a = 3.14 × (9)²

a = 3.14 × 81

a = 254.34 in²
