Detailed Solution
Download Solution PDFGiven:
The volume of the hemisphere is 19,404 cm3
Concept used:
The volume of a hemisphere = 2/3πr3
Here r = radius
Calculation:
According to the question,
2/3πr3 = 19404
⇒ 2/3 × 22/7 × r3 = 19404
⇒ 2/3 × 22/7 × r3 = 19404
⇒ r3 = 9261
⇒ r = 21
So, radius = 21 cm
∴ The radius of the hemisphere is 21 cm.
