The answer is true. use arc length=(central angle/2π)2πr.
The distance along a portion of the circumference of any circle or curve is best characterized as arc length (arc).
We know that the circumference of a circle is equal to 2πr. That means when we have 2π radians out of 2π radians (one hundred per cent of the circle).
If we are only dealing with part of the circle (sector), you find what per cent of the complete circle the sector is by dividing the central angle by 2π. In this case, we have 3 radians out of 2π radians,
Therefore we only have 47.75% of the circle. Because we only have a certain percentage of the circle, you multiply 2πr by the percent to get the arc length given by the sector.
In this case 0.4775x2xπx5 which equals 15.001 which is rounded down to 15 cm. Therefore the answer is true.

8 for plato users its D
-14, what is ✓k + m?
Submit
Answer:
3
Step-by-step explanation:
Evaluate:
Sqrt of k = 32 + m = -14
Sqrt of 32-14 = 9
Sqrt of 9 = 3
Therefore, our answer is 3!
Btw sqrt means: square root

If you are drawing only one marble then the probability of getting red and blue simultaneously is zero.
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
The Sum of all marbles in the bag is
8 + 4 + 5 = 17.
The Sum of red and blue marbles is
8 + 5 = 13.
Now, because you are picking only 1 marble it is impossible for it to be both red and blue. You would need to pick at least 2 marbles to have a chance that one is red and one is blue.
Therefore If you are drawing only one marble then the probability of getting red and blue simultaneously is zero.

This is a relatively close question, and I have tried multiple times. Can you help?
The distance an object falls when dropped from a tower varies directly as the square of the time it falls. If the object falls 144 feet in 3 seconds, how far will it fall in 18 seconds?
Answer: The one below is correct.
