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)
Answer:
25.12cm
Step-by-step explanation:
So we first find the area of the circle on top:
area= 
or 3.14 x
which equals 12.56
Then we multiply it by 2:
12.57 x 2 = 25.12
So the lateral surface area is 25.12cm
