Question

using clay , anant made a right circular cone of height 48 cm and base radius 12 cm. Varsha reshapes it in the form of a sphere. Find the radius and curved surface area of the sphere so formed.​

Answer 1

Answer:

12 cm

Step-by-step explanation:

We have,

h=48 cm

r=12 cm

We know that the volume of the cone

=

3

1

πr

2

h

=

×π×(12)

2

×(48) cm

Since, student reshapes it in the form of a sphere.

Let the radius of sphere be r.

So,

×π×(12)

2

×(48)

4×r

×(48)

r

=(12)

2

×12

r
