Answer:
The answer to your question is r = 4 in
Step-by-step explanation:
Data
Volume = 4000 π in³
height = 250 in
radius = ?
Process
1.- Look the formula to calculate the volume of a cylinder
Volume = πr²h
2.- Solve for r²
r² = Volume / πh
3.- Substitution
r² = 4000π / π(250)
4.- Simplification
r² = 16
r = √16
5.- Result
r = 4 in
Hey there mate ;)
As per question :-
<em>Write the word sentence as an inequality</em><em>.</em><em> </em><em>A number y is no more than −8.</em>
To make the sentence as an inequality, the answer will be:-
<h2> <u>
y < -8</u></h2>
Reason:-
By considering 'y' as a number, it is told that the number is not bigger than the value -8. So, by simple arithmetic, the answer will be <em>y</em><em> </em><em><</em><em> </em><em>-8</em>
He is incorrect
when dividing by ten, move the decimal 1 number to the right
he was sort of correct on the first part, but in the second part, the zero would automatically be removed, due to the fact that it comes after the decimal.
the correct answer for the second part is 2.316
hope this helps
cos (arctan (1))=
arctan (1) = 45 take it to the third quadrant = add 180 = 225
cos (225) = -1 / sqrt(2)
never leave a sqrt in the denominator
= -1 /sqrt(2) * sqrt(2)/sqrt(2)
= -sqrt(2)/2
sin (arccos (1/2)
arccos (1/2) = 60 take it to the 4th quadrant -60 degrees
sin (-60)
- sin 60
- sqrt(3)/2
