What is the length of xpy in terms of pie? a) 30 pi m b) 10 pi m c) 300 pi m d) 100 pi m

A

Step-by-step explanation:

The angle subtended at the centre of the circle by arc XPY is 270°

That is 360° - 90° = 270°

arc length = circumference × fraction of circle

                 = 2πr ×

                 = 2π × 20 ×

                 = 40π × = 30π m → A

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
