Question

question 8 of 10
what is the surface area of the right cone below?
15
6
a. 540π units²
b. 180π units²
c. 130π units²
d. 126π units²

Explanation:

Step1: Recall the formula for the surface area of a cone

The surface area formula of a cone is \(S=\pi r(r + l)\), where \(r\) is the radius and \(l\) is the slant height.

Step2: Substitute the given values into the formula

Given \(r = 6\) and \(l=15\). Substitute into \(S=\pi r(r + l)\):
