Two students, Matt and billy , each calculated the volume of a spherical ball with a diameter of 15 centimeters. their work is shown below

Answer:
Matt made the error
Step-by-step explanation:
Matt used the diameter of the sphere instead of the radius.
The student that made an error while calculating the volume of the spherical ball is Matt.
A sphere is the three-dimensional version of a circle/
Volume of a sphere = 4/3 x pi x r^3
Where:
pi = 22/7
r = radius = diamter / 2 = 15/2 = 7.5
4/3 x 7.5^3 x 22/7 = 562.50
