Question

Cone, diameter of base 18 ft slant height 14 ft

Answer 1

Answer:

207π ft²

Step-by-step explanation:

Given in the question,

diameter of the base  = 18 ft

slant height= 14 ft

radius of the base = 18/2

                              = 9 ft

Formula to calculate the surface area

A = πrl+πr²

here l = slant height

        r = radius of the base

plug values in the formula

A = π(9)(14)+π9²

A = 207π ft²
