Question

X 2. A solid wooden toy is in the shape0/5
of a cone mounted on a hemisphere
.if the radius of toy is 3.5 cm and it's
volume is 192.5 cm .find the total
hight of the toy.​

Answer 1

Answer:

Volume of the toy = Volume of the hemispherical part + Volume of conical part

Volume of a hemisphere of radius 'r' =32πr3

Volume of a cone =31πr2h  where r

is the radius of the base of the cone and h is the height.

The hemisphere and the cone will have the same radius r =4.2cm

Since total length of the toy is 10.2 cm, the length of the conical part will be 10.2−4.2=6cm

Hence, Volume of the solid =(32×722×4.23)+(31×722×4.22×6)=266.112cm3
