Question

If the circumference of the base of a solid right circular cone is 236 cm and its slant height is 12 cm. Find its curved surface area.

Answer 1

Hi,

According to the problem given,

the dimensions of the Solid right

circular cone are,

Slant height ( l ) = 12 cm

Circumference of

the base( C ) = 236cm

C = 2πr = 236 cm

πr = 236 / 2 = 118 cm ----( 1 )

Therefore ,

Curved surface area of

the cone ( A ) = πrl

= 118 × 12

= 1416 cm

Required curved surface area

of the cone =A = 1416 cm

I hope this helps you.
