Question

a solid is in the shape of a hemisphere surmounted by a cone if the radius of hemisphere and base radius of cone is 7 cm and height of cone is 3.5 cm find the volume of the solid

Answer 1

Answer:

This is the answer I had obtained

Answer 2

Answer:

The required volume is $2335.6cm^{3}$

Step-by-step explanation:

Volume is defined as the capacity or the amount that the vessel can hold.

It is given that radius of both hemisphere and cone is $7cm$

Height of cone is $3.5cm$

Now, volume of cone is $\frac{1}{3}$π$r^{2} h$

$=179.6cm^{3}$

Similarly volume of hemisphere is $\frac{2}{3}$π$r^{3}$

$=2156cm^{3}$

Total volume is sum of both

$=2156+179.6$

$=2335.6cm^{3}$
