The formula to find the area of a circle is A = πr^2, where A is the area and r is the radius. In this case, we are given the area of the circle (1,962.50 ft^2) and asked to find the diameter.
To find the radius, we can rearrange the formula and solve for r:
A = πr^2
1962.50 = πr^2
r^2 = 1962.50/π
r^2 ≈ 625
r ≈ √625
r ≈ 25
The diameter of a circle is twice the radius, so the diameter of the circle that Robert mowed is 2 * 25 = 50 feet.
Therefore, the correct answer is 50 feet.
Robert was bored cutting the lawn at his grandpa’s farm, so he decided to get creative. He mowed a large circle in one of the open pastures. The area of the circle was 1,962.50 feet2. What was the diameter of the circle that he mowed? Use 3.14 for 𝜋.
