Find the central angle measure of the sector of a circle that represents the givent percent

the percent is 28%.

How do I solve this.

 the central angle measure of the sector of a circle = 28% of 360 , as complete angle = 360 at center

    = 28*360/100

   = 100.8 degrees

How do you get that though I don't understand

May 22nd, 2015

total angle at center = 360

given sector is 28% of that 

calculate 28% of 360

required sector angle = (28/100)*360 

 28*360/100 = 28*36/10 = 1008/10 = 100.8

if not clear can ask again .

ok so its basically 28 over 100 = X over 360

and then we cross multiply

and get 10080=100x

then we divide by 100 and then that gets us 100.8

am I right ?

so for another example

to find the central angle measure of the sector of a circle that represents 15%

the answer would be 54 ?

yes it's right , if you have any other problem free feel to ask , good luck .

thankyou that is all

thankyou that is all


May 22nd, 2015

15/100 = x/360

x = 15*36/10 = 54

o k you are always wellcome .God bless .
