Answer:
130.43 cm³
Step-by-step explanation:
To find the difference between the volumes of the balls, we must first find the volumes of the balls. To find the volume of each ball, we must first determine their shape. We understand that both balls are spherical.
The volume V of a sphere wit radius r is given as
V = 4/3 πr³
where r is the result when the diameter of the sphere is divided by 2.
Hence the radius of the Golf ball
= 4.3cm/2
= 2.15cm
radius of the tennis ball
= 6.9cm/2
= 3.45cm
The difference between the volumes of the two balls
= 4/3 π (3.45³ - 2.15³)
= 130.43 cm³
I would be glad to help if you would show a picture of the prism :)
Answer:
The new median would be 15.
Step-by-step explanation:
This is because the median means the middle number so we can cross out 2 and 25. Then cross out 6 and 23. Then cross out 7 and 21. Next, cross out 14 and 20. Since there is only one number left, 15, that number is therefore the median.
<u>Given</u>:
Given that a basketball court is in the shape of a rectangle that is 94 feet long and 50 feet wide.
We need to determine the length of the diagonal to the court.
<u>Length of the diagonal:</u>
The length of the diagonal can be determined using the Pythagorean theorem.
Thus, we have;
where d is the diagonal, l is the length and w is the width of the rectangle.
Substituting the values, we have;
Thus, the length of the diagonal of the court is 106.5 feet.
