A toy is made in the form of hemisphere ...

A toy is made in the form of hemisphere sumounted by a right cone whose circular base is joined with the plane surface of the hemisphere . The radius of the base of the cone is 7 cm and its volume is `3/2` of the hemisphere . Calculate the height of the cone and the surface area of the toy correct to 2 places of decimal (Take `pi= 3 1/7`)

Text Solution

Verified by Experts

The correct Answer is:
Slant Height of cone (l) = 22.14 cm, Surface area of toy = `795.08 cm^2`
