Corrected Question
The volume of air inside a rubber ball with radius r can be found using the function V(r) = four-thirds pi r cubed. What does V(5/7) represent?
Answer:
(B)the volume of the rubber ball when the radius equals five-sevenths feet
Step-by-step explanation:
The Volume of a sphere of radius r can be found using the formula:
Therefore comparing the expression: with V(r):
Thus, is the volume of a ball of radius
feet.
The correct option is B.
we are given
5 equally sized boxes of cake mix fell off the back of Jake's truck
it means that
total number of balls =5
Together they weigh 925.98 pounds
total weighs =925.98 pounds
each ball weighs = (total weights)/(total number of balls)
now, we can plug values
each ball weighs =
each ball weighs is 185.196 pounds..................Answer
