You can also findout the answer in this way-: 15*18/5=54 Note:- If we want to convert percentage into degree then we will multiply by 18/5 and if we want to convert degree into percentage then we will multiply by 5/18. |

15% is the royalty as given in the ques. 10% = 36 degree, 1% = 3.6 degree there for 5% = 18 degree 10+5 = 36+18 15% = 54 simple. |

Would anyone please make understand what exactly the question has been asked? 'central angle of the sector' what does it mean? please help me. |

Archana said: (Jul 5, 2011) | |

Central angle means degree, total angle any circle is 360" degree that we measure using protractor. |

But its given corresponding sector. So we should have taken 15% of either 10% or 20% na? |

You can also find out the answer in this way: 15*3.6 = 54. NOTE-[1%=3.6]. |

15/100 = 0.15. 360*0.15 = 54. |

Why central angle correspond to the royalty? |

Jitendra Bharti said: (Oct 4, 2016) | |

If 15% of 360 than 10% is 36. Hence 5% is 18 now 15% is 54. |

All the ways are helpful and thank you for the solution. |

Mandar said: (Dec 16, 2016) | |

Now I understand the answer. Thanks for all your explanation. |

Here, How we get 360-degree? |

Bhavana said: (May 9, 2017) | |

The total angle in a circle 360 degrees. Royalty occupies 15% of the total. Thus the angle made by royalty is (15/100) *360 =54 degrees. |

I want to know the trick how to convert degree into a percentage? Please explain. |

Anonymous said: (Sep 23, 2017) | |

Percentage to degree ( X * 18/5). Ex- 15%= ?degree 15 * 18/5= 54degree Degree to percentage ( X * 5/18) Ex- 54degree =?% 54 * 5/18= 15%. |

How to make percent into degree? |

Ladva Dharmesh said: (Mar 17, 2018) | |

If any cost, expenditure can be found in pie chart only multiple 360 can find cost, expenditure. |

Sushmitha said: (Apr 26, 2018) | |

Why we take 15% of 360 can anyone explain me? |

Axel said: (Apr 30, 2018) | |

One circle is equal to 360 angles. |

Vishakha said: (Jul 13, 2018) | |

How 1% =3.6, It's not given 10% is 36. So, how it could be? |

Yeshey Wangchuk said: (Jul 21, 2018) | |

1% of 360°, 1÷ 100*360= 3.6°. So, 10% means 10÷100* 360. = 3.6° |

Sonam Penjor said: (Aug 2, 2018) | |

How comes 100 here? Please explain. |

Satyananda said: (Sep 18, 2019) | |

Thanks all. |

Akshatha said: (Jan 21, 2020) | |

If royalty=15% , promotion cost=10%. Then total=15+10=25%. For 25% encloses 90 degrees. For 15% encloses how much degrees? So, therefore( 90/25)*15=54°. |
