A) 808 cu cm
B) 800 cu cm
C) 816 cu cm
D) 824 cu cm
Correct Answer: A
Solution :
Given that, Outer radius of hemispherical shell (R) = 9 cm and inner radius of hemispherical shell (r) = 7 cm \[\therefore \]Volume of a hemispherical shell \[=\frac{2}{3}\pi \,\,({{R}^{3}}-{{r}^{3}})=\frac{2}{3}\times \frac{22}{7}\times (729-343)\] \[=\frac{2}{3}\times \frac{22}{7}\times 386=\frac{16984}{21}=808.76\] \[\approx 808\]cu cm (approx.)You need to login to perform this action.
