Answer:

r = 10 mm

Step-by-step explanation:

Formula of a quater circle perimeter: P = ( $\frac{\pi }{2}$ + 2 )r

You substitute the given perimeter then you'll have something that looks like this : 35.7 = ( $\frac{\pi }{2}$ +2)r

Then you divide both sides by ( $\frac{\pi }{2}$ +2) to get the answer

Answer:

The coterminal angles are : 270° , -450°

sketched angle is in third quadrant

Step-by-step explanation:

The sketch of the angle in standard position is attached below

The coterminal angles :

- 90 + 360 = 270°

-90 - 360 = -450°

Quadrant of the angle( -90° ) = Third quadrant
