Question

What is the volume of a hemisphere with a radius of 3.3 m, rounded to the nearest tenth of a cubic meter?

Answer 1

$\sf Hello!$

• $\sf Radius = 3.3 \:m$

$\sf Then,$

$\sf Volume \: of\:Hemisphere$ :

= $\dfrac{\sf 2}{\sf 3}$π$\sf r^{2}$

= $\dfrac{\sf 2}{\sf 3} × \sf 3.14 × \sf (3.3)^{2}$

= $\dfrac{\sf 2}{\sf 3} × \sf 3.14 × \sf 10.89$

= $\dfrac{\sf 2}{\sf 3} × \sf 34.1946$

= $\sf 22.\:79759998\: m^{3}$

= $\sf 22.8 \:m^{3}\: (approx.)$
