Answer:

33493.34

Step-by-step explanation:

r=20

volume of sphere= 4/3×πr^3

= 4/3×3.14×20^3

= 33493.34

or

r=20

volume of sphere= 4/3×πr^3

= 4/3×22/7×20^3

= 33523.80952

<h3><u>Answer:</u></h3>

\boxed{\boxed{\pink{\bf \leadsto The \ Volume \ of \ the\ sphere\ is\ 33493.33 \ in.^3 }}}

<h3><u>Step-by-step explanation:</u></h3>

According to the Question the radius of the sphere is 20 inches. And we know that the Volume of sphere is given by :-

\boxed{\orange{\sf Volume_{sphere}=\dfrac{4}{3}\pi r^3 }}

And here radius is 20 in.

\implies Volume = \dfrac{4}{3}\pi r^3 \\\\\implies Volume =\dfrac{4}{3}\times\dfrac{22}{7}\times (20 in.)^3\\\\\implies \boxed{\bf Volume = 33493.33 in^3 }

<h3><u>Hence</u><u> the</u><u> </u><u>Volume</u><u> of</u><u> the</u><u> </u><u>sphere</u><u> </u><u>is</u><u> </u><u>33</u><u>4</u><u>9</u><u>3</u><u>.</u><u>3</u><u>3</u><u> </u><u>inch³</u><u>. </u></h3>
