Question

A hamster ball has a radius of 21 centimeters. What is its volume written in terms of π?

12,348π cm3

6,946π cm3

588π cm3

9,261π cm3

Answer 1

\[V_{Sphere} = \frac 43πr^3\]

Answer 2

\[V_{Sphere} = (\frac 43)(π)(21^3)\]

Answer 3

And here r is radius which is given as 21 cm

Plug in the values of r = 21 and \(\pi = \frac{22}{7}\) and find the volume..

Answer 4

Well, it says leave in terms of π, so you would just leave the π alone.

Answer 5

Oh sorry I didn't see that..

Answer 6

I got 9265.18 ?

Answer 7

It is approx equal to D..

Answer 8

Not quite...\[\frac{4 \times 9261 \times π}{3}\]

Answer 9

Try dividing the 9261 and 3 first. Then multiply by 4.

Answer 10

So the answer is A?

Answer 11

Yup :)
