Surface Area of Cones Practice

Question

Math 8 Q2 (Pre-Algebra) / Cones, Cylinders, & Spheres

A waffle cone in the shape of a cone with a slant height of 8 in and a radius 3 in a Baker wants to know the surface area of the cone in order to cover the cone with melted chocolate what is the surface area of the side of the cone in square inches use 3.14 for pi and round to the nearest hundred

Answer 1

The surface area of the side of a cone can be calculated using the formula:

SA = π * r * l

where SA is the surface area, r is the radius, and l is the slant height.

Given:
Radius (r) = 3 in
Slant height (l) = 8 in
π (pi) = 3.14

Substituting the given values into the formula, we have:

SA = 3.14 * 3 * 8
SA = 75.36 in²

Therefore, the surface area of the side of the cone is approximately 75.36 square inches.
