Step-by-step explanation:
Answer:
d. V = π(x^3 + 90x^2 + 2,400x + 20,000)
Step-by-step explanation:
volume of cylinder = πr^2h
We have r = x + 20; h = x + 50
V = π(x + 20)^2(x + 50)
V = π(x^2 + 40x + 400)(x + 50)
V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)
V = π(x^3 + 90x^2 + 2,400x + 20,000)
To find x:
Subtract 10 on both sides.
10 + 2x = 90
-10 -10
Divide 2 on both sides.
2x = 80
--- ---
2 2
This would get x alone.
x = 40
Check:
10 + 2(40) = 90
10 + 80 = 90
90 = 90
The value of x is 40. The angle degree of it is 80 when you multiply 2 by 40.
