The formula for a cylinder is πr²*h where r is the radius and h is the height:
1.) Plug in r for 4, as the radius is 4
π(4)²*h
2.) Plug in h for 8, as the height is 8
π(4)²*8
3.) Simplify 4²
π(16)8
4.) Simplify 16*8
π128
5.) Don't forget your units, inches cubed (because you multiplied three dimensions all with inches, which results in the inches being multiplied three times as well)
π128 in³ or 128πin³
It is the third answer choice, hope this helped :)

Answer:
the last one is 30
Step-by-step explanation:
Step-by-step explanation:
1 hour = 60 minutes
40 minutes out of an hour can be written as: 40/60
Fraction = 40/60
= (2 × 30) / (3 × 20)
Canceling out common factors of numerator and denominator, we get 2/3
Therefore, 40 minutes is 2/3 of an hour.
Sosksl 35is40 is 40 times 0 is 3
