Answer
Substituting 29 cm into the area formula, we get π*(29 cm)^2 = 2642.1 cm^2. Hence, the area of the circle is approximately 2642.1 cm^2.
Explanation
In this question, we are given the diameter of a circle and asked to calculate the area of the circle. This is a two-step process. 1. Determine the radius of the circle. The radius is half of the diameter. As the problem provided that the diameter is 58 cm, the radius of the circle is 58/2 = 29 cm. 2. With the radius, we can then use the formula for calculating the area of a circle, which is πr^2 (pi times the radius squared). Doing this operation should give us our desired solution.
