Find the arc length of the partial circle.

kodGreya [7K]

Answer:

Arc length of the partial circle = 3π units

Step-by-step explanation:

Given question is incomplete; please find the complete question attached.

Formula for the arc length of a circle = $\frac{\theta}{360^\circ}(2\pi r)$

Here θ is the angle formed by the sector at the center.

Angle that is formed at the center of the circle is = 360° - 90°

= 270°

So, length of the arc = $\frac{270}{360}(2\pi)(2)$

= 3π

Therefore, length of the given partial circle is 3π units.

If one real number is equal to a second real number, and the second real number is equal to a third real number, then the first

svet-max [94.6K]

Answer: In particular, let’s focus our attention on the behavior of each graph at and around . 2 and x= -1 for x < 2. There are open circles at both endpoints (2, 1) and (-2, 1). The third is h (x) = 1 / (x-2)^2, in which the function curves asymptotically towards y=0 and x=2 in quadrants one and two."

These two scalene triangles are similar with a scale of 4:5. What is true about these figures?

disa [49]

Alright, lets get started.

Lets check each possible answer one by one.

We will start from option B.

BC is from small triangle and its corresponding side is DF, so its ratio will be $\frac{4}{5}$ not $\frac{5}{4}$ as given in option. Hence option B is incorrect.

For option C,

Angle a° and angle f° are not similar angles, if they were similar, then only their ratio will be 1 otherwise not 1. Hence option C is incorrect.

For option D,

Angle c° and angle f° are similar angles so, their ratio will be $\frac{c}{f} = 1$ . Hence option D is incorrect.

Now option A,

ED and AB are corresponding sides. ED is from bigger triangle and AB is from smaller triangle. Their ratio will be $\frac{ED}{AB} = \frac{5}{4}$ . Hence option A is correct answer.
