Question

A cone has a circular base of radius 13.5 m. Given
that the total surface area of the cone is 1240 m²,
find its volume.​

Answer 1

Answer:

Given

Radius = 13.5 m

Total surface area = 1240 m^2 .

ATP

πr (l+r ) =1240

π= pie

l= slant height

t= radius .

Find the slant height according to the problem of Total surface area of cone

Then find the volume of

cone i. e.

Volume =1/3πr^2h .
