Answer:
50 degrees
Step-by-step explanation:
If angle A and angle B are complementary, that would mean that their sum is 90 degrees. A + B = 90 . We know that angle A is 40, so 40 + B = 90. It becomes a one step equation. Subtract both sides by 40. 90 - 40 = 50. Angle B is equal to 50 degrees.
Answer:

Step-by-step explanation:
The volume of a cylinder,
is given by the formula,

Where,
is the radius and
is the height of the cylinder.
Here,
,
. Plug in these values and solve for radius,
.
This gives,

Taking square root both sides, we get

Therefore, the radius of the cylinder can be expressed as
.
Base times height and you have your answer
