Answer:
113.1
Step-by-step explanation:
This is the formula you have to follow, finding the volume of objects is hard without the formula and it's just something you'll have to memorize. BUt just remember to plug in the radius which is 3 in this problem, into the volume formula: 
Answer:
1.68 ft
Step-by-step explanation:
Let x be the radius
Arc length = 3.14x
Width = 2x
Height = [12 - (2x) - 3.14x]/2
= 6 - 2.57x
Area = 3.14x²/2 + 2x(6 - 2.57x)
Area = 12x - 3.57x²
dA/dx = 12 - 7.14x = 0
x = 1.6806722689
Height = 6 - 2.57x
= 1.6806722689
Answer:
x= -8
Step-by-step explanation:
Since you know y=8 you plug it into the equation
-4x -8=24
you then add 8 to each side
-4x=32
then divide by -4
x=-8
Answer:
45
Step-by-step explanation:
Every Triangle has 180 degrees.
x + 8x + 3x = 180
12x = 180
x = 180/12
x = 15
Angle K = 3x
K = 3 * 15
K = 45
