Question

calculate the area of the circle. area of a circle: 3.14×r² a = ? ft² round to the nearest hundredth.

Explanation:

Step1: Find the radius.

The diameter $d = 14$ ft, and the radius $r=\frac{d}{2}=\frac{14}{2}=7$ ft.

Step2: Calculate the area.

The formula for the area of a circle is $A = 3.14\times r^{2}$. Substitute $r = 7$ into the formula: $A=3.14\times7^{2}=3.14\times49 = 153.86$ ft².

Answer:

$153.86$
