Answer 1

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)) = (4)/(3) × π × r³}}`

Where,

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

`\small\sf{ Volume_((sphere)) = (4)/(3) × 3 × 2³}`

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

`\rightarrow \small\sf{ Volume_((sphere)) = 4 * 8 = 32}`

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

Answer 2

V = 32

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
