We substitute r with the radius of this cylinder and the h represents the height of this cylinder. The height we can find because we just add the diameters of the tennis balls. So 2.6*3 = 7.8. Then we get the radius, which will just be the radius of a sphere, so 1.3. Then we plug them into the formula, giving us 74.33
The probability is 50% for heads, so you should expect 2 heads results
21x-9+6y
combining terms: 4x+17x=21x
