Answer:
a) 84π b) 109.2π
Step-by-step explanation:
The formula to find this is v=πr^2h/3
r=d/2. so the radius (r) is 6 because you have to divide the diameter (12) by 2. and the height is 7. so, 6^2=36 and 36x7=252.
252/3=84
and because the question is asking for the EXACT value, you need to just put the pi symbol next to it. Final answer for a is 84π
B) you need to find 30% of 84, which is 25.2 and add it to 84, and you will get 109.2! Final answer is 109.2π.

Step-by-step explanation:
Hi there! :)

h(x) = 1/2x + 4
Substitute in -4 for "x" to solve for h(-4):
h(-4) = 1/2(-4) + 4
h(-4) = -2 + 4
h(-4) = 2
Since we are solving for h(-4) + 2, add:
2 + 2 = 4.
Answer:
33.6
Step-by-step explanation:
The following data set shows the numbers of hours that employees at a certain shop worked in one week
34 36 32 40 39 17 35 33 36 34
The mean is the average of the numbers. It is easy to calculate - add up all the numbers, then divide by how many numbers there are.
Hence,
