Since 2*pi*r = 132cm
=) 2* 22/7 * r = 132cm
=) r = 132*7 / 2*22 cm
=) r = 21cm
Since V of hemisphere = 2/3 * pi *r^3
=) V = 2/3 * 22/7 * 21*21*21 cm^3
=) V = 19,404 cm^3
Since 1 cm^3 have capacity of 1ml.
Hence the capacity of the bowl is 19404 ml or 19L 404ml.
Hope it's helpful to u.

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
