The answer is D.
The formula for the volume of a sphere is
You would divide the diameter in half which would give you your radius (r).
Then you plug in the radius value to find the volume of ONE ball.
You would then multiply by 10 to find the volume of TEN golf balls.
D is the closest answer to the volume of ten golf balls

The dot plots is an illustration of charts and graphs
The average score of period 7 is greater than the average score of period 1
<h3>How to determine the period with the higher average?</h3>From the dot plots in the complete question, we have the following frequency tables
<u>Period 1</u> <u>Period 7</u>
Score Students Score Students
55 1 65 1
70 1 75 3
75 6 80 5
80 6 85 6
85 2 90 3
90 3 95 2
95 1
The average is calculated using:
For period 1, we have:
Evaluate the sum
Evaluate the quotient
For period 7, we have:
Evaluate the sum
Evaluate the quotient
By comparison, 83 is greater than 79.5
Hence, the average score of period 7 is greater than the average score of period 1
