a spherical ball bearing has a diameter of 18 mm.find the volume of 50 such ball bearings and give your answer in cm3. (take pie=3.14)
Answer:
152.604 cm³
Step-by-step explanation:
a spherical ball bearing has a diameter of 18 mm.find the volume of 50 such ball bearings and give your answer in cm3. (take pie=3.14)
Given: d = 18 mm
r = (1/2)d = 9 mm
10 mm = 1 cm
r = 0.9 cm
number of ball bearings (n) = 50
Find: total volume of 50 ball bearings (cm³)
Solution:
Volume of 1 ball = (4/3) × (3.14) × (r)³
Volume of 1 ball = (4/3) × (3.14) × (0.9 cm)³
Volume of 1 ball = 3.05208 cm³
Total volume = n × volume of 1 ball
Total volume = 50 × 3.05208 cm³
Total volume = 152.604 cm³
