If 16 candy bars is $20, then each candy bar is $1.25, which means 24 candy bars would cost $30.
The area of a trapezoid = 0.5h(a + b) where a and b are the lengths of the parallel sides
so here we have 0.5(8)(a + 12) = 144
solve for a
4(a + 12) = 144
4a + 48 = 144
4a = 96
a = 96/4 = 24

The formula for calculating the height is h = 3V/πr²
<h3>Subject of the formula</h3>
The formula given is the formula for calculating the volume of a cone
V = 1/3πr²h
where
h is the height
r is the radius
Make h the subject of the formula
Cross multiply
3V = πr²h
Divide both sides by πr²
3V/πr² = πr²h/πr²
h = 3V/πr²
Hence the formula for calculating the height is h = 3V/πr²

If one kit contains 235 parts, then all we need to do to find out how many are in 4 of those same kits is multiply the amount in one kit by the amount of kits there are.
235 * 4 = 940
There are 940 parts in 4 of the kits.
Hope that helped! =)
