The friend is wrong - According to the Pythagorean Theorm, if c is the hypotenuse and a and b are opposite sides then c^{2} = a^{2} + b^{2}
if c=65 inches, a=16 inches and b = 63 inches, then
65^{2} =16 ^{2} + 63^{2}
right hand side of the equation = 256 + 3969 = 4225
left hand side of the equation = 65^{2}= 4225
So we see, left hand side = right hand side
Hence the theorm is proved.

Step-by-step explanation:
Answer:
V ≈ 37.7 ft³
Step-by-step explanation:
Volume is the area of the end times the height
V = πR²h
V = 3.14(4/2)²(3)
V = 37.68 ≈ 37.7 ft³
1/4 is the correct answer
