Answer: 11.76
Step-by-step explanation:
The formula for cylinder is pi*r^2*h
so substitute and you will get pi*1.44*2.6
Simplify it and you will get 11.75616 or 11.76.

The pizza pirate ate the whole pizza!
2(days) + 3(a few days) = 5
20 x 5 = 100%
Therefore, the whole pizza is gone. Don't worry, I'll buy a new one!
Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3
<h3>
How to get the volume of the sphere?</h3>
For a sphere of radius R, the volume is given by the formula:

In this case, we can see that the diameter is 9 cm, then the radius is half of that:
R = 9cm/2 = 4.5cm
Now that we know the radius, we can replace it on the volume formula to get:
