The inflated

The inflated gymnastic ball should have a diameter of 65 cm. How many times do we have to pump air into a fully blown ball with a bicycle inflator to inflate it if the working volume of the inflator is a cylinder with an inner diameter of 2 cm and a height of 25 cm? (round the result to tens).

Correct answer:

n =  1830

Step-by-step explanation:

D=65 cm r=D/2=65/2=652=3212=32.5 cm  V=43 π r3=43 3.1416 32.53143793.3137 cm3  D2=2 cm h=25 cm r2=D2/2=2/2=1 cm  V2=π r22 h=3.1416 12 2578.5398 cm3  n1=V/V2=143793.3137/78.5398=109856=1830561830.8333  n=[n1/10] 10=[1830.8333/10] 10=1830
