Answer: 1.61 minutes
Step-by-step explanation:
The shape of a volleyball is a sphere. The formula for calculating the volume of a sphere is
Volume = 4/3 x πr^3
where
r represents radius
π is a constant whose value is 3.14
From the information given,
diameter = 10 inches
radius = diameter/2 = 10/2 = 5
radius = 5
By substituting these values into the formula,
Volume = 4/3 x 3.14 x 5^3
Volume = 523.33 in^3
If a pumpkin inflate the ball at a rate of 325 in^3 per minute, the time it will take to inflate the ball is
523.33/325
= 1.61 minutes
