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.
Given:
The base of the triangle = 8.6 yd
The height of the triangle = 10.9 yd
To find the area of the triangle.
Formula
The area of a triangle with b as base and h as height is
Now,
Taking, b= 8.6 and h = 10.9 we get,
sq yd
or, sq yd
Hence,
The area of the given triangle is 46.87 sq yd.
