7th Grade Pre- Algebra
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
= 100.8 degrees
How do you get that though I don't understand
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
15/100 = x/360
x = 15*36/10 = 54
o k you are always wellcome .God bless .
