If the length of the 45° region of this circle is 10 inches, what is the radius of the circle? Use and round to the nearest tent
USPshnik [31]

Answer:

12.71in

step explanation:

The Length of an arc given is expressed as;

A = theta/360 * 2πr

10 = 45/360 * 2 * 3.14r

10 = 1/8 * 6.28r

Cross multiply

10 * 8 = 6.28r

80 = 6.28r

r = 80/6.28

r = 12.74in

Hence the radius is 12.71in

pashok25 [27]

Answer:

The fraction is 470/1000, which can be simplified to 47/100, and that is 47%.

Step-by-step explanation:

Basically you take what is asked for and you divide it by the total amount.

470 is the amount of girls as contestants.

1000 is the total amount of contestants.

And that gives you the ratio 470/1000.

Hope this helped!
