Question

If the volume of hemisphere is 19404 cm then find its radius

Answer 1

Given : Volume of Hemisphere = 19404 cm³

To find : Radius of Hemisphere

$\boxed{\boxed{\tt{Solution :- }}}$

To find the radius, we will use the following formula of Hemisphere

Volume of Hemisphere ☛ $\dfrac{2}{3}$πr³

☛ 19404 = $\dfrac{2}{3} \times \dfrac{22}{7}$r³

☛ r³ = $\dfrac{19404 \times 7 \times 3}{22 \times 2}$

☛ r³ = $\dfrac{407484}{44}$

☛ r³ = 9261

∴ r = 21


∴ $\pink{\underline{\pink{\underline{\tt{\red{The\:radius\:is\:of\:21\:cm}}}}}}$

Answer 2

formula of sphere =4/3 pai r cube

Step-by-step explanation:

a/q-

19404=2/3 pai r cube

19404 * 3/2 * 7/22=r cube

9261=r cube

r=∛9261

r=21
