circumference of circle =132
2 pie r= 132
2×22/7×r= 132
44/7×r=132
r=132×7/44
r=21
volume of the hemispherical bowl =2/3 pie r^3
=2/3×22/7×21×21×21
=2/3×22/7×9261
= 44/ 21 ×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
