Answer:

Step-by-step explanation:
In this cross sections problem, we can integrate from -r to +r (so that the integral covers the entire base of the solid).

The formatting for the integral did not let me put -r on the lower bound, so i replaced it with a, just know that a represents -r here.
Evaluating the integral gives use that it is equal to;

Step-by-step explanation:
we know that
The algebraic expression of seven-tenths is equal to the number 7 divided by ten

The algebraic expression of the product of 5p and 3 is equal to multiply 5p by 3

therefore
The algebraic expression of seven-tenths of the product of 5p and 3 is equal to

Answer:
x = 18
Step-by-step explanation:
To solve this problem, we can use the exterior angle theorem, which means the measure of an exterior angle is the sum of its remote interior angles. In this case, this would mean:
x + 72 = 5x
Since this gives us an equation, we can just solve for x:
x + 72 = 5x
72 = 4x
x = 18
