Answer:
68 degrees
Step-by-step explanation:
2 complementary angles make up a 90 degree angle.
90 degrees - 22 degrees = 68 degrees
Since the radicands (the number under the radical) are the same, add the coefficients and keep the radicand.
4√5 + 2√5 = 6√5

The volume of a cylinder is given by

where
is the base area, and
is the height.
We are already given the height, which is 10.
We can deduce the base area since we are given a diameter: the radius is half the diameter, so it's 8, and the area of a circle is given by

So, the volume is

The total number of minutes for all casses is 150 minutes
Step-by-step explanation:
Find the cost of one part and then multiply that number by 9
