Question

1. which of the following formulas is used to calculate the area of the base of a cone? a. \\( \frac { 1 } { 3 } \pi r ^ { 2 } \\) b. \\( \pi r ^ { 2 } h \\) c. \\( \pi r ^ { 2 } \\) d. \\( \frac { 4 } { 3 } \pi r ^ { 3 } \\)

Explanation:

Step1: Recall the shape of the base of a cone

The base of a cone is a circle.

Step2: Recall the formula for the area of a circle

The formula for the area of a circle is \(A = \pi r^{2}\), where \(r\) is the radius of the circle.

Answer:

C. \(\pi r^{2}\)
