Question

the ciecumference of the edge of a hemispherical bowl is 132cm find its capacity

Answer 1

circumference of the hemisphere=2πr/2

=πr

so,

22/7*r=132

r=132*7/22

r=6*7

=42cm

volume of the hemisphere=2/3πr^3

=2/3*22/7*42*42*42

155232cm^3 is the answer

Answer 2

Answer : 19404 sq.cm

Formula used :

$circumference = 2 \: \pi \: r$

$volume \: of \: hemisphere \: = \frac{2}{3} \: \pi \: {r}^{2}$
