Question

What is the capacity of a hemisphere having circumferences is 132 cm

Answer 1

Answer:

2πr=132

2.22/7.r=132

44/7r=132

r=132×7/44

r=21

Again capacity of hemisphere= volume of hemisphere

=2/3πr³

=2/3.22/7.(21)³

=19404.

Answer 2

As we know that :

Perimeter or Circumference of hemisphere = 2R+πR

According to the question :

2R+πR = 132

$= > r(2 + \frac{22}{7} ) = 132 \\ \\ = > r = \frac{132 \times 7}{14 + 22} \\ \\ = > r = \frac{132 \times 7}{36} = 25.67$

Now, Capacity or volume of Hemisphere :

$\frac{2}{3} \pi {r}^{3} \\ \\ = > \frac{2}{3} \times \frac{22}{7} \times {(25.67)}^{3} \\ \\ = > 35441.41 \: {cm}^{3}$
