Its sideways and I cant read it
Answer:
9
Step-by-step explanation:
Pythagorean Theorem
a²+b²=c²
(c² is the hypotenuse)
a² + 40² = 41²
a² + 1,600 = 1,681
subtract 1681-1600 in order to isolate a², which is the missing leg we are trying to find
a² = 81 in order to find our answer, we isolate a by squaring both sides
√a² = √81
a = 9
Our answer is 9.
V=pi a^2*h
V= 3,14*100*18 cm^3=5652 cm^3
Answer is 5652
