Hi so what I’m going to do is help you on how to do 3/8 divided by 6:7 in kfc form.

So just a reminder a KFC form is keep (the first fraction), flip(the second fraction) and change (the sign from division to multiplication)

What you need to do is flip the reciprocal meaning that you need to divide it by the fraction and multiply the reciprocal of that denominator and flip it into a numerator

So first we had 3/8 divided by 7/6

Now we flip 7/6 and turn it to a 6/7

So then now we fixed the problem and it turned out to be 3/8 divided by 7/6

After that you flipped the second fraction you then change the division operation into a multiplication operation

So it’s 3/8x7/6

You then crossed out 6 and replace it into a 2 and as for 3 you replace it into a 1 since you’re simplifying from both separate sides.

Now you are left with 1/8x7/2

You now multiply it and now you are left with
7/16 because you had to find a common denominator which is 16 since 8x2=16 and 2x8=16

Therefore your final answer is going to be 7/16.

Answer from: Quest

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
