Question

A cylindrical bucket of diameter 28 cm and height 20 cm was full of sand. When the sand in the bucket was poured on the ground, the sand got converted into a shape of a cone. If the height of the cone was 14 cm, what was the base area of the cone?

Answer 1

Given: For the cylindrical bucket, 

diameter (d) = 28 cm, 

height (h) = 20 cm 

For the conical heap of sand, height (H) = 14 cm 

To find: Base area of the cone (πR ). 

Diameter of the bucket (d) = 28 cm

The base area of the cone is 2640 cm² .
