Volume of baseball is 1.24 times greater than volume of tennis ball.
We are given the diameter of baseball and tennis ball. So, firstly we will calculate the volume of tennis ball and baseball.
Volume of ball = 4/3πr³, where r stands for radius of ball.
Taking value of π as 3.14.
Volume of tennis ball = 4/3×π×2.7³
Volume of tennis ball = 82.4 m³
Volume of baseball = 4/3×π×2.9³
Volume of baseball = 102.1 m³
Now, finding the number of times volume of baseball is greater than volume of tennis ball.
Comparison - volume of baseball ÷ volume of tennis ball
Comparison - 102.1 ÷ 82.4
Comparison - 1.24
Hence, volume of baseball is 1.24 times of volume of tennis ball.
