Answer:
= 2 pi x^3
Step-by-step explanation:
radius = x
h = 2x
The volume of a cylinder is
V = pi r^2 h
= pi ( x) ^2 ( 2x)
= 2 pi x^3

c is the answer
Step-by-step explanation:
Answer: B.
Explanation:
Consider any right triangle that has both its legs of same length. In this case both the other two angles would be 45 degrees each. Now, if both its legs are considered of unit length, then hypotenuse would be of length √2.
The cos 45 = 1/√ 2 = √ 2/2
Hope this helped! :)
