Answer 5

Well you have the circumference ,so can you find the radius?

Answer 6

reply ?

Answer 7

Hint: the distance from X to Y along the circle is exactly one-quarter of the distance around the entire circle

this is because the central angle XZY is 90 degrees and 90 degrees is 1/4 of 360 degrees

Answer 8

ya thats a better method :)

Answer 9

okay so you do 84 divided by 4?

Answer 10

as jim said you just need to understand , the arc length also will have same proporion

Answer 11

I got 21 :)

Answer 12

yep :)
