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)

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
