V = π r² h
V = π (4)² 8
V = 402.12
Hope this helps :)
7.5 ft because
6/30 = .0005 so then x we factor in equals 7.5 for
The formula for working out the total interior is:
180(n-2) = 1260
So let’s rearrange by dividing both sides by 180 and find what n is:
n-2 = 7
Then let’s add 2 to both sides to find what n is:
n=9
Each interior angle is 1260/9 = 140°.
The sum of the interior angle and its corresponding exterior angle is 180°.
Therefore, the polygon has 9 sides. :)
The value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90
<h3>How to evaluate the expression?</h3>
The expression is given as:
5x – 2y + (7x – y)
Substitute x = 7 and y = –2 in the above expression
5 * 7 - 2 * -2 + (7 * 7 + 2)
Evaluate the expression
90
Hence, the value of the expression 5x – 2y + (7x – y) when x = 7 and y = -2 is 90
