circumference = 2 x 22/7 x radius (r)
132 = 2 x 22/7 x r
r = 132/2 x 7/22
r = 21 cm
capacity = 2/3 x 22/7 x r x r x r
= 2/3 x 22/7 x 9261
= 19404 cm^3
132 = 2 x 22/7 x r
r = 132/2 x 7/22
r = 21 cm
capacity = 2/3 x 22/7 x r x r x r
= 2/3 x 22/7 x 9261
= 19404 cm^3

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
