We have been given that in a circle an arc length 10 is intercepted by a central angle of 2/3. We are supposed to find the radius of the circle.
We will use arc-length formula to solve our given problem.
, where,
= Arc length,
= Radius,
= Central angle corresponding to arc length.
Upon substituting our given values in arc-length formula, we will get:
![10=r\cdot \frac{2}{3}](https://tex.z-dn.net/?f=10%3Dr%5Ccdot%20%5Cfrac%7B2%7D%7B3%7D)
![10\cdot \frac{3}{2}=r\cdot \frac{2}{3}\cdot \frac{3}{2}](https://tex.z-dn.net/?f=10%5Ccdot%20%5Cfrac%7B3%7D%7B2%7D%3Dr%5Ccdot%20%5Cfrac%7B2%7D%7B3%7D%5Ccdot%20%5Cfrac%7B3%7D%7B2%7D)
![5\cdot \frac{3}{1}=r](https://tex.z-dn.net/?f=5%5Ccdot%20%5Cfrac%7B3%7D%7B1%7D%3Dr)
![15=r](https://tex.z-dn.net/?f=15%3Dr)
Therefore, the radius of the given circle would be 15 units.
Answer: <u>the rotation of earth on its axis and revolution</u>
Step-by-step explanation:
The earth revolves round the sun and rotates round its own axis. The rotation of the earth causes day and night. The part of the earth which faces the sun experiences the day time whereas the part away from sun gets no sun light and hence the night. ... The axis of earth's rotation is tilted at 23.5 degrees.
