Question

WILL MARK BRAINLIEST TO THE BEST ANSWER. PLEASE SHOW ALL WORK IN FULL SOLUTIONS. THANK YOU. A basketball has a diameter of 7.4 cm, Which expression represents the volume of the basketball?
A) 4pi(3.7)^3
B) 4pi(7.4)^3
C) 4pi(7.4)^3/3
D) 4pi(3.7)^3/3

Answer 1

I think the answer is A.

the formula to find the volume of a sphere is 4/3 x pi x radius cubed. this means you have to split the diameter in half giving you 3.7 which automatically rules out the answers with 7.4 written in them. now you have to compare A and D but D has 3/3 at the end. this is where you can see that it’s wrong because when you cube you don’t use a fraction.
