\The sphere's radius is half the radius of the hemisphere. How does the volume of this hemisphere compare with the volume of the sphere?

4 : 1 or 4 times

Step-by-step explanation:

V of sphere is

V = 4/3 π r³

then we can compare both of them dirextly

Vs : Vhs

4/3 π r³ : ½ (4/3 π (2r)³)

4/3 π r³ : ½ * 4/3 π 8r³

1 : ½ * 8

1 : 4

Vhs : Vs = 4 : 1

so the volume of hemisphere is 4 times bigger than the sphere.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
