Answer:
81.64
Step-by-step explanation:
formula for volume of a cylinder is pi times radius squared times height
the radius here is 2, and the height is 6.5
plug the numbers into the formula and you get pi(2^2)(6.5), which is 81.64
Answer:
44 degrees
Step-by-step explanation:
The angles x + 2 and x are complementary; they sum up to 90 degrees.
Thus, x + 2 + x = 90 degrees, or:
2x = 88, or
x = 44.
The value of x is 44 degrees.

Step-by-step explanation:
1. R is the set of all integers with absolute value less than 10, thus
2. A is its subset containing all natural numbers less than 10, thus
3. B is the set of all integer solutions of inequality 2x+5<9 that are less than 10 by absolute value (and therefore, it is also a subset of R). First, solve the inequality:
Thus,
See the diagram in attached diagram.
Note that
I dont know but i think either B or A
Answer:
50.1 deg F
Step-by-step explanation:
1.6deg F for every 1,000ft. You need to get to 9,000ft. 1.6degx9=14.4
64.5deg-14.4deg=50.1degF
