Question

csa of hemisphere is 905 1/7 what is its volume

Answer 1

HEY!!
THE ANSWER IS HERE,

CSA of hemisphere = 905 1/7 =6336/7

$2\pi {r}^{2} = \frac{6336}{7}$

${r}^{2} = \frac{6336}{7} \times \frac{7}{44}$

r => 144

$r = \sqrt{144} = 12$

$volume = \frac{2}{3} \pi {r}^{3}$

$= > \: \frac{2}{3} \times \frac{22}{7} \times {12}^{3}$

=> 3620.571 cubic cm

:-)Hope it helps u.

Answer 2

CSA =905 1/7
2 πr² =6336/7
2×22/7 r² = =6336/7

44r²= 6336

r²=6336/44=144
r=√144=12

Volume = 2/3 πr³
             =2/3×22/7×12³ = 3620.571428...unit³
