Question

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

Answer 1

Circumference=
$2\pi \: r$
2×22/7×r=132. => r=21 cm..... Volume = 2/3
$\pi \: r$
It's pi r cube =>2/3×22/7×21×21×21. =>2×22×21×21= 19404 cm
cube.........

Answer 2

given 2πr=132
22 / 7 x r=132/2
22/7. x r=66
r=66x7/22
r=3x7
r=21cm

so capacity of bowl =volume of hemisphere
=2/3π r³
= 2/3x22/7x21x21x21
= 2x22x21x21
v. =19404cm³
