This should be relatively easy, since most of us have learned and used the formula for the volume of a sphere: V = (4/3)* pi* r^3.
Just combine (4/3)pi into a single value, k, which results in V = kr^3.
This looks like: 
To solve this problem, you'll want to use the AC method to factor x^2+7x-30.
After factoring your expression will look like this:

Cancel out the x+10 because they are common factors, so you are just left with the simple x-3.
Answer is:
x - 3
You can find the perimeter by just counting the distance of every line segment all around the shape since they have vertical and horizontal slopes.
Answer:
d. $350.00
Step-by-step explanation:
A constant is a number that does not have any variables. The additional cost would depend on the number of persons at attendance so the cost would be $10.00p which is not the constant here. Thus, $350.00 is the only constant in this situation.
