Question

the circumference of a circular park is approximately 30 feet. what is the approximate area inside the circular park? what is the approximate area inside the park? solve on paper. then, enter your answer on zearn. remember, you can use 3.14 as an approximation for π. consider writing your answer to the hundredths place. the area inside the park is approximately square feet.

Explanation:

Step1: Find the radius from the circumference

The formula for the circumference of a circle is \(C = 2\pi r\). Given \(C=30\) feet and \(\pi\approx3.14\), we can solve for \(r\):

$$r=\frac{C}{2\pi}=\frac{30}{2\times3.14}=\frac{30}{6.28}\approx4.78$$

Step2: Calculate the area of the circle

The formula for the area of a circle is \(A=\pi r^{2}\). Substitute \(r\approx4.78\) and \(\pi = 3.14\) into the formula:

$$A=3.14\times(4.78)^{2}=3.14\times22.85=71.75$$

Answer:

\(71.75\)
