Answer: 16 m
Step-by-step explanation:
We have the following data:
is the velocity of the object moving in uniform circular motion
is the time it takes to the object to go of a complete circle
We need to find the radius of the circle, and this can be found by the following equation:
(1)
Where is the circumference of the circle and is the period for a complete circle.
Hence, isolating we have:
(2)
(3)
Finally:
(4)
The answer would be C. You should get a second opinion, though. Also, if this is right, can you rank me Brainliest? Thanks!
Now, if you notice the picture, the arcRSQ is 280°, since a circle has a total of 360°, then the arcRQ is 360° - 280°, or just 80°.
keeping in mind that arc's get their angle measurement from the central angle they're in, well, in this case the central angle for arcRQ is ∡ROQ, sor ∡ROQ = arcRQ.
Answer:
3.8 x 10^6
Step-by-step explanation:
Answer:
70
Step-by-step explanation:
An angle on the circle is half of the intercepted arc. Since the circle is 360, you can subtract 220 from 360 and find the intercepted arc which is 140. Divide that by 2 and you get 70.
