Formula: V = (2/3) π r 3.

Radius is 3cm.

So, now we can plug it in to solve for the volume.

V = (2/3) π 3^3

First, let's multiply 3^3.

3^3 = 27

Then, 27 x π = 84.82

After, multiply by 2/3.

84.82 x 2/3 = 56.55

Lastly, round 56.55 to the nearest tenth of a cubic centimeter.

56.55 = 56.6

Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

The Volume of sphere whose radius is 3 cm = 113 [tex]cm^{3}[/tex] (rounded to the nearest tenth)

Volume= 113 [tex]cm^{3}[/tex]

What is Volume of sphere?

The volume of a sphere = 4/3 r³, where r is the radius of the sphere.

Volume of sphere = [tex]\frac{4}{3} * \pi* r^{3}[/tex]

                               = [tex]\frac{4}{3} * 3.14* (3)^{3}[/tex]

                               = 4 x 3.14 x 9

                               =113.04 [tex]cm^{3}[/tex]

                               ≈ 113 [tex]cm^{3}[/tex] (rounded to the nearest tenth)
