Answer:

V = 32

Step-by-step explanation:

Comment

I think you should try this one yourself after I post my answer. Estimation is a very valuable tool -- the more you use it, the handier it gets.

Formulas

pi = 3

V = 4/3 * pi * r^3

Givens

r = 2

pi = 3

Solution

V  = 4/3 * pi * r^3                     Substitute values for symbols

V = 4/3 * 3 * 2^3                      Cancel the 3s

V = 4 * 2^3                               Expand the 2s

V = 4 * 2 * 2 * 2                       Find V

V = 32

Answer 2

Explanation -:

In this question we are provided with the radius of a sphere. We are asked to calculate the volume of the sphere.

$\large \: \star\small\boxed{ \rm{ Volume_{(sphere)} = \dfrac{4}{3} × π × r³}}$

Where,

• r stand for radius.
• Assuming π as 3.

$\small\sf{ Volume_{(sphere)} = \dfrac{4}{3} × 3 × 2³}$

$\rightarrow \small\sf{ Volume_{(sphere)} = \dfrac{4}{ \cancel{3}} × \cancel {3} × 8}$

$\rightarrow \small\sf{ Volume_{(sphere)} = 4 \times 8 = 32}$

$\bull \: \small \underline{ \boxed{\sf{ Volume_{(sphere)} = 32 {cm}^{3} }}}$
