a can of soup has a volume of 20 pi cubic inches. the diameter of the can is 4 inches. What is the height of the can

5 inches

Step-by-step explanation:

A can is cylindrical in nature and volume of a cylinder is expressed as;

V = πr²h where;

r is the radius of the cylindrical can

h is the height of the can.

Given parameters

Volume of the can of soup = 20πin³

diameter of the can = 4inches

Since diameter = 2r

radius = d/2 = 4/2 = 2inches

Required parameter.

Height of the can

Substituting the given parameters into the formula to get the height h will give;

20π = πr²h

20 = r²h

20 = 2²h

20 = 4h

Divide both sides by 4:

4h/4 = 20/4

h = 5inches

Hence the heighr of the can is 5 inches

I would tell Eddie that he is correct if the coin is a fair coin (not weighted to favor one side).  Since coins have two sides, heads and tails, the probability of getting heads is 1 out of 2 or 1/2.  Same for tails (1 out of 2 or 1/2)
Since 325 is half of 650   (325/650 = 1/2) we know that the probability of getting heads in 650 flips is 1/2 or 325

In reality we might expect it not to be exactly 325 heads - could be 321 or 329 or even 338.   But we would not expect 35 heads and 615 tails.
