Andru [333]

The height of the cone is 4 cm (approx).

Step-by-step explanation:

Given,

The radius (r) of the cone = 4.96 cm

Volume (V) = 102 cm³

To find the height (h) of the cone.

Formula

The volume of a cone V = \frac{1}{3}πr²h

Now,

According to the problem,

\frac{1}{3}πr²h = 102

or,  \frac{1}{3}×\frac{22}{7}×(4.96)²h= 102

or, h = \frac{102X7X3}{4.96^{2}X22 }

or, h = 3.95 = 4 (approx)

so,

Height = 4 cm (approx)
