The volume of a cone is 471.24 cubic inches and the height is 8 inches. What is the diameter
Vladimir [108]
The volume of a cone is V = 1/3 pi r^2 h
h = 8
pi = 3.14
V =471.24
r = ??? 
d = ???

471.24 = 3.14 * 8 * r^2
471.24 = 25.12 * r^2
471.24 / 25.12 = r^2
18.76 = r^2
r = sqrt(18.76)
r = 4.312

The diameter is 2*4.312 = 4.624 in. <<<<<==== answer.

The lengths of three sides of a quadrilateral are shown below:
pentagon [3]
In part A, we need to solve for the total length of sides 1, 2 and 3.
Since all three sides measurements are given, we have the solution below:
Sides123 = Side 1 + Side 2 + Side 3
Sides123 = (3y² + 2y - 6) + (4y² + 3y -7) + (5y² + 4y -8)
Sides123 = 12y² + 9y - 21
This is the total length of sides 1,2 and 3 "12y² + 9y - 21"

In part B, we need to solve for the length of the fourth side and the solution is shown below:
Side 4 = Perimeter / Sides123
Side 4 = (4y³ + 18y² + 16y -26) / 12y² + 9y -21
