Answer:
1256 in³
Explanation:
To calculate volume of a cylinder the formula is: π · r2 · h
Since Pi is already given to us as 3.14, we now have to find the radius
The radius is always the diameter cut in half meaning it will be 20/2 which gives us 10 (radius is figured)
The height is given to us as 4 meaning the equation will be
3.14 x 10 x 10(seeing as it's radius squared) x 4
10x10 = 100
100 x 4 = 400
400 x 3.14 = 1256
The answer is in cubed(³) because it is volume
