If the radius goes through 1 rotation. The "angle" gone through is 360 degrees. So the method is to figure out circumference of the circle, multiply this by a fraction involving 120, and you are done.
Formula
Arc Length = (120/360) * 2 * pi * r Substitute values into this equation.
Givens
Central angle = 120
r = 9.5
Solution
Arc Length = (120/360) * 2 * 3.14 * 9.5
Arc Length = (0.333) * 2 * 3.14 * 9.5
Arc Length = 19.87 cm
Weird. I think you just need to look if the point falls on the shaded area. But only (-5,5) does ...
Answer:
y=x and y=2/3x
Step-by-step explanation:
Every point on line a has an equal x and y value so y=x. For line b, the y value of every point is 2/3 of the x value. So at (3,2) 2/3 of 3(the x value) is 2(the y value).
Answer:
Rounding is selected to match the precision required. Rounding to the nearest hundredth provides better precision than rounding to the nearest tenth.
Explanation.
Suppose you calculate the value of a variable x as $300.0143.
Because $0.143 or 14.3 cents is not available, we round 14.3 cents to 14 cents, and x = $300.14.
In this case, we have rounded to the nearest hundredth.
If you do not want to be bothered with pennies, you ignore the four pennies and round 14 cents to 10 cents, and x = $300.10.
In this case, we have rounded to the nearest tenth.
