Answer:
1/2x
Step-by-step explanation:

To solve this type of fraction you need to times the inverse of the bottom fractal, both over and under. In this case the inverse of 1/2 is 2/1
Step-by-step explanation:
- volume of cylinder=90π
- πr²h=90π
- 3²h=90
- 9h=90
- h=90/9
- h=10
hope it helps.
To determine the area if the circle, you must know the diameter or the radius of a circle.
If you know the radius of a circle, use this as your formula. Remember: Pi (the greek symbol thingy) is equal to 3.1415. (A is equal to area of the circle and r represents the radius)

If you know the diameter, just divide the diameter to get the radius then use the same equation.
Answer:
angle 2, 4, 6 are 34 degrees
angle 7, 5, 1, 3 are 146 degrees
180-34= 146
Answer:
Line BE = 180 degrees
Therefore, angle BAD + angle DAE = 180 degrees
Angle DAE = 180 -110 = 70 degrees
