Question

A Cone of height 20cm and radius of base 5cm is made up
of modeling clay. A child reshapes it in the form of a sphere.
Find the radius of the sphere.​

Answer 1

Answer:

Step-by-step explanation:

=Radius of the cone = r = 5cm

and

Height of the cone = h = 20cm

Let the radius of the sphere = R As per given statement

, Volume of sphere = Volume of cone 4/3 πR3 = 1/3πr2h

4R3 = 5 × 5 × 20

R = 5 cm

Diameter of the sphere = 2R = 2 x 5 = 10 cm
