About 2.86 inches
Step by step explanation-
The formula for the volume of a cone is pi2 h/3 plugging the known numbers into formula you get
75=pi 5^2 h/2
H/3=0.955
H=2.86 inches
No.
If a rational number can be an integer, x and y could be 5.5 and .5, or something that adds up to (number).0. This means, if the two non-rational numbers add up, they could be irrational, but the result isn't.
Multiply the top one by 3 for x, so you can eliminate x and find y
then plug in the y into one of the equations to find x
Y2-y1/x2-x1. so -7-8/-1-(-1)= -15/1
So if you do 6(pi) then you should get 18.84
