Answer: Susan, sam forgot to flip the signs while dividing a negative number.
V = pi r^2 h
v = 3.14 * 5^2 * 15
v = 3.14 * 25 * 15
v = 1177.5 in^3
Tell you what I'll do: I'll show you the work, for two of them.
Then, knowing how to do it, you'll find the answers.
Deal ?
#1). n + (-13) = -12
Remove the parentheses
on the left side: n - 13 = -12
Add 13 to each side: n = 1
================================
#3). -15 + n = 3
Add 15 to each side: n = 18
OK. Look those over, understand how they're done, then TAKE IT !
So First of all we need to know how to find the area of a circle.
Assuming that the apple pie is the shape of a circle
The formula for area is
Well we know that the radius = 3.14
And we know that = 3.14 as well.
All we have to do is multiply..
3.14 x = 30.95
So the area of the pie is 30.95 in
Good Luck! :)
