Ineed with these two questions.

1. what is the volume of this sphere? (first picture)

8π cm³

16π cm³

27π cm³

36π cm³

2. what is the volume of this sphere? (second picture)

use 3.14 for pi and round to the nearest hundredth when necessary.

615.44 cm³

2461.76 cm³

11,488.21 cm³

91,905.71 cm³

(1) Volume of a sphere is .

(2)volume of the sphere is 11488.21 cm³ .

Step-by-step explanation:

Formula

Where r is the radius of the sphere .

Part First

As given the radius of the circle is 3cm .

Putting values in the formula

Therefore the volume of a sphere is .

Second Part

As given

Diameter of the sphere is 28 cm .

Putting all the values in the formula

Therefore the volume of the sphere is 11488.21 cm³ .
