Question

express the required calculation in terms of $pi$ and then round to the nearest tenth. how much fencing is required to enclose a circular garden whose radius is 26 meters? there are of fencing required. (simplify your answer. type an exact answer in terms of $pi$.)

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius.

Step2: Substitute radius value

Given $r = 26$ meters, substituting into the formula gives $C=2\pi\times26 = 52\pi$ meters.

Step3: Calculate approximate value

Using $\pi\approx3.14$, we have $C\approx52\times3.14 = 163.28$ meters. Rounding to the nearest tenth, $C\approx163.3$ meters.

Answer:

Exact answer: $52\pi$ meters
Approximate answer: $163.3$ meters
