The volume of hemisphere x2 + y2 + z2 = 9, z ≥ 0 is given by (a)

1.	The volume of hemisphere x2 + y2 + z2 = 9, z ≥ 0 is given by (a) 36π(b) 9π (c) 18π(d) 27π
Answer» Radius of hemisphere is r = 3 (By comparing x² + y² + z² = r²) \(\therefore\) Volume of hemisphere = \(\frac23\pi r^3\) = \(\frac23\pi\times3^3\) = 18\(\pi\)

The volume of hemisphere x2 + y2 + z2 = 9, z ≥ 0 is given by (a) 36π(b) 9π (c) 18π(d) 27π

Answer»

Radius of hemisphere is r = 3

(By comparing x² + y² + z² = r²)

\(\therefore\) Volume of hemisphere = \(\frac23\pi r^3\)

= \(\frac23\pi\times3^3\) = 18\(\pi\)
