Question

The volume of a cone-shaped dessert is 10 CUBIC CENTIMETRES.

The RADIUS of the Cone is 2 CM.

Find the height of the CONE, to the NEAREST TENTH.
ANSWERS
1. 0.4 CM
2. 1.4 CM
3. 2.4 CM
4. 4.4 CM

Answer 1

3. 2.4 c.m

The height of the cone 'h' = 2.4 c.m

Explanation:

Explanation:-

Given radius of the cone = 2 cm

Given data

The volume of a cone-shaped dessert is 10 cubic centimetres

The Volume of the Cone

`V = (1)/(3) \pi r^(2)h`

`10 = (1)/(3) X 3.14 X (2)^(2) X h`

cross multiplication , we get

`h = ( 3 X 10)/(3.14 X 4)`

h = 2.388 ≅ 2.4 c.m

The height of the cone 'h' = 2.4 c.m
