Question

Find the lateral area of a cone with a radius of 7 ft. and a slant height of 13 ft use 3.14 for

Answer 1

To find the lateral surface area, use the following formula
la = π × r × s

Given:
π = 3.14
r = 7 ft
s = 13 ft

Solution
Input the numbers to the formula
la = π × r × s
la = 3.14 × 7 × 13
la = 285.74

The lateral surface area of the cone is 285.74 square feet
