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:
x= -19
Step-by-step explanation:
1. subtract 4 from both sides
-15 - 4= -19
Answer:
147
Step-by-step explanation:
We want to find the value of a² + √b, so let's plug in 12 for a and 9 for b:
a² + √b
12² + √9
The square root of 9 is 3 because 3 * 3 = 9, while the square of 12 is 144 because 12 * 12 = 144.
144 + 3 = 147
The answer is thus 147.
