Question

find the area and the circumference of a circle with radius 7 ft. use the value 3.14 for π, and do not round your answers. be sure to include the correct units in your answers.

Explanation:

Step1: Calculate the area of the circle

The formula for the area of a circle is \(A = \pi r^{2}\). Given \(r = 7\) ft and \(\pi=3.14\), substitute into the formula:
\(A=3.14\times7^{2}=3.14\times49\)

Step2: Calculate the circumference of the circle

The formula for the circumference of a circle is \(C = 2\pi r\). Given \(r = 7\) ft and \(\pi = 3.14\), substitute into the formula:
\(C=2\times3.14\times7\)

Answer:

Area: \(153.86\ \text{ft}^2\)
Circumference: \(43.96\ \text{ft}\)
