Question

Find the volume of each sphere

Answer 1

Heyo! ;D

Volume for Sphere 1 = 9,202.77

Explanation:

Considering we need to find the radius of this sphere to determine the volume, we need to break the given diameter in half. Also, since we know that half of 26 is 13, we can safely say that the radius of the sphere is 13. Now, we can follow the given formula for finding volume of spheres:

V = 4/3 x $\pi$ x r^3

   = 4/3 x $\pi$ x 13^3

   = 9202.77

I am not entirely sure how to round to two decimal places, however considering on what you have learned in your class, I'm sure you can take this from here.

Volume for Sphere 2 = 5,575.28

Explanation:

Taking into count that we already have our given radius, we can go right to the formula for finding volume of a sphere:

V = 4/3 x $\pi$ x r^3

   = 4/3 x $\pi$ x 11^3

   = 5575.27

Round to the nearest tenth place, leaving you with 5575.28.

Again, I have no idea what you have learned in your class, however I am sure you can round it from here.

Hope this helped you at least get closer to the answers you seek! If you have any questions, feel free to comment below. Good luck!

Answer 2

Answer: 1) 9198.11

              2) 5572.45

Step-by-step explanation:

The formula for the volume of a sphere is V=4/3 π $r^{3}$

The radius of the first sphere is 13 plug it into the formula for r

$13^{3}$ = 2197

2197 x 3.14 = 6898.58

6898.58 x 4/3 = 9198.11

Do the same for the second sphere:

$11^{3}$ = 1331

1331 x 3.14 = 4197.34

4197.34 x 4/3 = 5572.45
