Question

The volume of a sphere is given below where r is the radius of the sphere. What is

the approximate radius, in units, of a sphere that has a volume of 164.636 units
cubed?
V = 4/3pi*r^3
o 3.4
o 4.1 o 7.3
o 39.3
( i really need help )

Answer 1

This is just a guess but I think it’s b

Answer 2

Answer: 3.4

Explanation:

V=4/3•pi•(r)^3

164.636=4/3•pi•(r)^3

164.636/(4/3•pi)= 39.3…

39.3=(r)^3

*cubed root of both sides* r=3.399… so r=3.4
