Answer:
V =192 pi units^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the radius is 8 and the height is 3
V = pi (8)^2 *3
V =192 pi units^3

Answer:
x = 7/2 (or 3 1/2 or 3.5)
Step-by-step explanation:
2x + 5 = 12
2x = 7
x = 7/2 (or 3 1/2 or 3.5)
For some reason, the scores your teacher gave you and the answer choices don't match up. I'm not sure why this is. Perhaps some kind of typo. Please double check and get back to me.
Answer:
B
Step-by-step explanation:
The mean is the average found by adding the sum of the data points and dividing by the number of them. Here there are 3 cars whose speeds are 109, 111, and Z or unknown. The mean of them is 100. Solve for Z.
100 =(109+111+Z)/3
300=220+Z
80=Z
The speed of Car Z is less than 100.
