The slant height of an icecream cone is 12 cm and its curved surface area is 113.04 sq cm. What is the radius of the base of this cone? (π = 3.14)

Question

Philoid · Accepted Answer

We have

Given: slant height of the cone, l = 12 cm

Curved surface area of the cone, CSA = 113.04 cm²

We know curved surface area of cone is given by

CSA = πrl, where r = radius of the base of the cone

⇒ r = CSA/πl

Substituting the given values in the above equation, we get

⇒

⇒ r = 3

Thus, radius is 3 cm.
