Answer:

V = 33.49

SA = 100.48

Step-by-step explanation:

lunathemoonchild13
The volume of a sphere has a formula of

V = 4/3 pi(3.14 in this case) r^3

r (radius) = 2

Let’s plug in the numbers

4/3 (3.14) (2) ^3

All of this is equal to 33.49393...

Or 33.5 since we round it to the tenth

The surface area

The formula is 4 pi(3.14) r^2

r = 2

Let’s plug in

4 (3.14) (2)^2

This is equal to 50.24

To the tenth it’s 50.2

V: 33.5 cm ^3
SA: 50.2 cm ^2
