The volume of a cone is equal to 13 times the area of the base πr2 π r 2 times the height h . Substitute the values of the radius r=6 and height h=8 into the formula to find the volume of the cone. Pi π is approximately equal to 3.14
Answer:
Number 1 is 12.
Step-by-step explanation:
{Solve by cross multiplication}
17 • x = 3 • (80 - x)
{Multiply 3 by distribution,}
17x = 240 - 3x
{Add 3x to both sides of the equation,}
20x = 240
{Divide through out by 20,}
20r/20 = 240/20
x = 12
Thus there were 12 pens :)
