Question

1. approsiamently how much fencing is needed to enclose a circular pond with a diamater of 12.5 feet

Explanation:

Step1: Recall the formula for the circumference of a circle

The formula for the circumference of a circle is \(C=\pi d\), where \(d\) is the diameter.

Step2: Substitute the given diameter into the formula

Given \(d = 12.5\) feet and using \(\pi\approx3.14\), we have \(C\approx3.14\times12.5\).

Step3: Calculate the value

\(3.14\times12.5=(3 + 0.14)\times12.5=3\times12.5+0.14\times12.5 = 37.5+1.75=39.25\)

Answer:

D. \(39.25\) ft
