Answer:
D) 20 in
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h where r is the radius and h is the height
Substituting what we know
980 pi = pi (7)^2 h
Divide each side by pi
980 pi /pi= pi 49 h/pi
980 = 49h
Divide each side by 49
980/49 = 49h/49
20 =h
Answer:
6.07/212
Step-by-step explanation:
Answer:
60 degrees.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
2x + 1 = 85 (Alternate Interior Angles Theorem)
2x = 84
<em>x = 42</em>
(3y + 5) + (2x + 1) = 180 (Linear Pair Theorem)
3y + 5 + (85) = 180
3y + 5 = 95
3y = 90
<em>y = 30</em>
Perimeter = 2L + 2W
Perimeter = 2(4x^2) + 2(y^2)
Perimeter = 8x^2 + 2y^2
x^2 - 7x^2 = -6x^2
-3x - -2x = -3x +2x = -x
8 - -1 = 8+1 = 9
Answer = -6x^2 -x + 9
9x^2 -4x - 3x^2 -2x
9x^2 - 3x^2 = 6x^2
-4x - -2x = -4x +2x = -2x
Answer = 6x^2 -2x
