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]
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)
