For the first one just do the multiplication as you do normally.
For the second one, you have to put a zero behind before calculating the numbers in front
Answer:
60 degrees
Step-by-step explanation:
Angles 1 and 2 are "corresponding angles" and as such are equal. Thus, the measure of angle 2 is 60 degrees.
Answer: The volume of the pipe is 412 cubic feet
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder = π x radius² x height (Length in this case)
Replacing with the values given:
V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet (rounded)
In conclusion, the volume of the pipe is 412 cubic feet

The acceptable first step in simplifying the expression 
is (a) 
The expression is given as:
To change the form of the expression, we simply perform several arithmetic operations on it.
Start by multiplying the expression by 1/1
Express 1 /1 as (1 - sec x)/(1 - sec x)
Rewrite the above expression as follows:
Hence, the acceptable first step is (a)
