Answer: 8.48 Feet
Step-by-step explanation:
We can use the Pythagorean Theorem, A^2 + B^2 = C^2
A^2 + B^2 = C^2
A^2 + 3^2 = 9^2
A^2 + 9 = 81
81 - 9 = A^2
72 = A^2
√72 = A
8.48 = A

So for these equations you want to solve for Y
Simply the equation till you get something that looks like Y=X+5 (or any number)
Then plug in the X into your equation
SA=4pir^2
V=(4/3)hpir^2
given
SA=36pi
36pi=4pir^2
divide by 4pi
9=r^2
sqrt both sides
3=r
v=(4/3)pir^3
v=(4/3)pi3^3
V=4pi9
v=36pi
36pi cubic feet
The answer is 7.5 Hope it helps!
