Question

The circumference of a edge of a hemisphere bowl is 132cm find the capacity of the bowl

Answer 1

Answer:

let the radius be x cm

$2\pi \: r = 132$

$2 \times 22 \div 7 \times r = 132$

r=21 cm

capacity=

$2 \div 3\pi \: r {}^{3}$

19404

Answer 2

Answer:

circumference=132 cm

2πr = 132 cm

2 × 22/7× r = 132

44/7 x r = 132

r= 132 x 7/44

r = 21

volume of hemisphere = 2/3 πr³

=2/3 x 22/7 x 21x21x21

=44x 441

=19404 cm³
