Answer:
324 inches cubed
Step-by-step explanation:
The volume of a cylinder is given by the formula: V = r^2 * h, where r is radius and h is the height.
Here, r = 6 and h = 9. So: V = * (6^2) * 9 = * 36 * 9 = 324
Thus, the answer is 324 inches cubed.
Hope this helps!
Answer:
x=-2 x=-1
Step-by-step explanation:
2x^2 + 6x = -4
Add 4 to each side
2x^2 + 6x +4= -4+4
2x^2 + 6x +4=0
Factor out 2
2( x^2 +3x+2) = 0
Divide by 2
x^2 +3x +2 =0
( x+2)(x+1) =0
Using the zero product property
x+2 =0 x+1 =0
x=-2 x=-1
Start at 107...
107 (-9) = 98
98 (- 8) = 90
90 (-7) = 83
83 (-6) = 77
77 (-5) = 72
72 (-4) = 68
68 (-3) = 65
The formula of a lateral area of a triangular prism is
LA = (1/2)*(perimeter of a triangle)*h
The perimeter of a triangle is the total of all sides.
Since the length of the base of a triangle is not given yet, use the Pythagorean theorem
base² = 7² + 24<span>²
base</span><span>² = 625
base = 25 cm
The perimeter is 7 + 24 + 25 = 56 cm
Finally the lateral area is
LA = (1/2)*56*30 = 840 cm</span><span>²</span>
