We have that the formula of the volume of a Sphere is
a.
the radius of the sphere is r=2
the volume will be
b.
the radius of the sphere is r=4
the volume will be
c. as we can see the radius of the sphere b, is twice the radius of sphere a, but as we can see because we calculated the volume of spheres, the volume of the sphere b is much bigger than the twice of the volume of the sphere a. It is because we don't have a linear relationship because we have an exponent 3 in the radius in the formula of the volume

Answer:
B. DC = 29 and DE = 44.5
Step-by-step explanation:
I honestly don't know how to get DE but because DC has to be 29, the second option is the only right answer
Answer:
6 = r
Step-by-step explanation:
V = 
πr³ Use this equation to find the volume of a hemisphere
144π = πr³ Divide both sides by π
216 = r³ Take the cube root of both sides
6 = r

Answer:
x = 10
Step-by-step explanation:
Given:
Arc LM = 13x - 10
Arc MN = 7x - 10
Required:
Solve for x
Solution:
Recall: half a circle = 180°
Therefore,
Arc LM + Arc MN = 180°
13x - 10 + 7x - 10 = 180
Add like terms
20x - 20 = 180
20x - 20 + 20 = 180 + 20
20x = 200
20x/20 = 200/20
x = 10
