Step-by-step explanation:
Total volume of the hemisphere is equal to half of the volume of a sphere. Assume the radius of the sphere as 'r' and use the formula for volume of hemisphere =2πr33.
✪ Question ✪
Find the volume of a solid hemisphere of radius 2 cm.
✪ Given ✪
Radius = 2 cm
✪ To find ✪
The volume.
✪ Formula ✪
Volume of hemisphere = 2/3πr³, where r = radius.
✪ Solution ✪
Radius = 2 cm
π = 22/7 = 3.14
So, take 2 instead of r in the formula.
Volume = 2/3πr³ unit³
= (2/3 × 22/7 × 2³) cm³
= {(2 × 22 × 8)/(3 × 7)} cm³
= (352/21) cm³
✪ Hence ✪
Volume = 352/21 cm³
✪ Therefore ✪
The volume of the hemisphere is 352/21 cm³.
