Aball bearing is shaped like a sphere and has a diameter of 2.5 cm. what is the volume contained inside the ball bearing? use 3.14 for pi. round your answer to the nearest hundredth.

8.18 cm3
7.15 cm3
7.08 cm3
6.89 cm3

8.18 cm³

Step-by-step explanation:

Formula for Volume:

V=4 /3πr³ = (4/3π)1.25³ =  8.1812308687234 cm3³

divide 2.5 cm in half and you'll get 1.25

Radiusr = 1.25 cm

volumeV = 8.1812308687234 cm3³

surface areaA = 19.634954084936 cm2²

circumferenceC = 7.8539816339745 cm

853.3
