Answer: 1. 35.35 ; 2. 58.9
1. The equation of a volume is V=pi *r^2 * h
Our diameter is three, which means our radius is half of that or 1.5 and our height is 5. Our new equation will be V= pi* 1.5^2 * 5 That equals 35.3429174, which rounds to 35.34.
So our volume is 35.34
2. The equation once again is V=pi* r^2 * h
Our diameter is five, and half of that is 2.5, and our height is 3. Our new equation is V=pi *2.5 * 3. That equals 58.90486, which rounds to 58.9
So our volume is 58.9
I was not sure if you needed the answer rounded so I just put the whole answer and the answer rounded.
I hope this helped & Good Luck <3 !!
