Question

A solid cone of base radius 4 cm has a curved surface area of 100 cm^2. Find the slant height of the cone.

Answer 1

Answer: 7.96

Step-by-step explanation:

formula for curved surface area of cone=  πrl

Given:

curved surface area of cone = 100 cm^-2

base radius of cone = 4cm

Process:

πrl= 100

use π as 3.14

3.14*4*l=100

12.56*l=100

l=100/12.56

l=7.961
