Answer: 1539π cubic inches.
Step-by-step explanation:
In the figure, we have a hemisphere joined with a cylinder of the same diameter 18 inches.
Radius = 9 inches (half of diamter)
Volume of hemisphere = 
Volume of cylinder = 
, where r= radius h= height
Volume of hemisphere= 
Volume of cylinder = 
Combined volume = 486π+1053π=1539π cubic inches.
Hence, the volume of the solid = 1539π cubic inches.
Answer:
Composition of f and g = 6x + 7
Composition of g and f = 6x + 11
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x + 2
f(g(x)) = 2(g(x)) + 3 = 2(3x + 2) + 3 = 6x + 4 + 3 = 6x + 7
g(f(x)) = 3(f(x)) + 2 = 3(2x + 3) + 2 = 6x + 9 + 2 = 6x + 11
Its a square, so all the sides are equal. Also, since the area of a square (rectangles) is equal to the height times the length, which are both the same, the area of the square is equal to x², where x is the length of any one side of the square, x²=256. now you square root both sides of that equation, x=√256, and the square root of 256 is 16.
Tl;Dr: each side is 16 feet long.
Answer:
B is the answer
Step-by-step explanation:
f(x) = 20x + 4
20(0) + 4 = 0 + 4 = 4
20(1) + 4 = 20 + 4 = 24 . . .
The Coefficients is the number before the variable so in this case the coefficients are
24
3 or -3
and 7
Hope this helps!
