Two students, Matt and Billy , each calculated the volume of a spherical ball with a dime tee of 15 centimeters. Their work is s

Aleksandr-060686 [28]

Answer:

Matt ;

Used diameter of the ball instead of Radius

Step-by-step explanation:

The volume of a sphere is given as :

4/3πr³

Radius, r = diameter / 2

Given that, the diameter = 15 cm ; The Radius = 15 / 2 = 7.5 cm

Matt made an error in his calculation by failing to covert the value of the diameter given to Radius.

By dividing the diameter by 2 = 15 / 2 = 7.5, we obtain the Radius, which is what Billy did in her own calculation.
