Question

In the diagram below what is the approximate length of the minor arc XY

Answer 1

Hello!

As you can see, the radius is 27 cm, and we have a 60 degree angle. We will convert this degree into radians to find our answer.

$\frac{\pi}{180} (60)$≈1.05

Now we multiply this by our radius,

1.05(27)=28.35≈28.3

Therefore, our answer is C) 28.3 cm

I hope this helps!

Answer 2

C = 2pi r= 2 (3.14) (27) = 169.56

Let XY = x

169.56 / 360 = x / 60

360x = 169.56 * 60

360x = 10173.60

x = 28.26

x = 28.3

Answer is C. 28.3 cm
