Question

The total surface area of a right circular cone with the slant height 25cm is 704 sq. cm . Find the volume of the cone.

HELP PLEASE !!!​

Answer 1

area=πr√{h^2+r^2}

area=704cm^2, Height(h) =25cm

therefore,

by solving, πr√{h^2+r^2}=704cm^2

you will get value of r.

now, volume=πr^2×h/3

putting all values answer will come
