Question

1. a tank has a 10 foot radius. what is its circumference and area?

Explanation:

Step1: Calculate the circumference

The formula for the circumference of a circle is \(C = 2\pi r\). Given \(r = 10\) feet, substitute into the formula:
\(C=2\times\pi\times10 = 20\pi\approx20\times3.14 = 62.8\) feet.

Step2: Calculate the area

The formula for the area of a circle is \(A=\pi r^{2}\). Substitute \(r = 10\) feet:
\(A=\pi\times10^{2}=100\pi\approx100\times3.14 = 314\) square feet.

Answer:

The circumference is approximately \(62.8\) feet and the area is approximately \(314\) square feet.
