Answer:
They will pay the same amount!
1. The Formula to getting the area of a circle is pi r^2= 3.14 times the radius squared. Plug in the number given in the question to get your answer.
2. The Circumference formula is 2pir which is 2 time 3.14 times the radius given. Plug in the number to get your answer.
3. This one is giving you the diameter, therefore you need to divide the diameter by 2 to get the radius (diameter is twice the size of radius) and plug in the radius into the first formula (3.14 times r^2) to get your answer.
Answer:
V = 882pi units^3
or approximately
2769.48 units^3
Step-by-step explanation:
The column of a cylinder is given by
V = pi * r^2 * h
We know the radius is 7 and the height is 18
V = pi * 7^2 *18
V =pi *49 *18
V =882 pi
If we want an approximate answer, we can approximate pi by 3.14
V = 3.14 * 882
V =2769.48
