The volume of a cylinder is 81 pi in^3 and the height of the cylinder is 1 in. What is the radius of the​ cylinder
ladessa [460]

Answer:

18/20π

Step-by-step explanation:

81π ÷ 1 = 81π

81π ÷2 = 18/20π

You do this because the radius is half of the diameter and you need to get rid of the hight by dividing it from the volume.

Please help ill mark brainliesta​
alexdok [17]

Answer: Neither

Step-by-step explanation:

y = -5/4 x + 3/4

y = 5/4 x + 3/4

Because -5/4 is not a negative reciprocal of 5/4 and because they are not the same, they are neither in parallel or perpendicular

EGG DROP The physics class is holding an egg drop competition. The formula h= −16t2+h0 can be used to approximate the number of
WITCHER [35]

By solving a quadratic equation we will see that the egg will hit the ground after 1.58 seconds.

<h3>How long will take the egg to reach the ground?</h3>

Here we know that the initial height of the egg is 40ft, so the equation for the height will be:

h(t) = -16*t^2 + 40

The egg will hit the ground when h(t) = 0, so we need to solve the quadratic equation:

h(t) = -16*t^2 + 40 = 0\\\\16t^2 = 40\\\\t^2 = 40/16\\\\t = \sqrt{40/16} = 1.58

This means that the egg will hit the ground after 1.58 seconds.
