You have to know the formula for the volume of a cone.
In high school, there's no other way.
Volume of a cone = (1 / 3) π (radius)² (height)
Volume = (1 / 3) π (12 inches)² (15 inches)
Volume = 720 π = 2,261.95 cubic inches
Rounded to the nearest cubic inch, that's<u> 2,262 cubic inches</u>.
7/5 * 5/7y = 7/5 * 6
y = 42/5.
The multiplication property of equality is used.
-867, -145, -12.1, 12110
Note that a negative number converts a number to a very small number..
You would take 8.50 and divide it by 12.
to get $0.71
