Answer:
(d) 2/3(11)
Step-by-step explanation:
The height of the cylinder is h=2r, so the volume of the cylinder in terms of radius is ...
V = πr^2·h = πr^2·(2r) = 2πr^3
The volume of the sphere is given by the formula ...
V = (4/3)πr^3
So, the ratio of the sphere volume to the cylinder volume is ...
sphere volume / cylinder volume = ((4/3)πr^3)/(2πr^3) = (4/3)/2 = 2/3
That is, the sphere volume is ...
sphere volume = (2/3) × (cylinder volume)
V = (2/3)(11)
Answer:
28
Step-by-step explanation:
We use the concept of similarity to find the value of X.
Δ APR ≡ ΔCDR
∴ AR/CR = PR/DR
(10+x)/x = (15+42)/42
42(10+x) = 57x
420 + 42x = 57x
57x - 42x = 420
15x = 420
x = 420/15
= 28
I believe the answer is 6
45/100 is 4,500%
2/5 is 40%
18/40 is 45%
15/25 is 60%
