problems I first work out the whole circumference, and then work
out the fraction for the arc. So cancel a 2 top and bottom and
it's done. Now for question 10. What you have done is exactly
right so something else is wrong here. I started the next lesson
about Circumference and Arc Length and I got all the 18/20 No I
did #20 and got it correct You are very welcome. Thank you for
the help! Yes, that's it. Excellent! The thing is this. There is
a property that is always true for all circles and Q19 is
testing it. is always a right angle right? I said #102 before
seeing post #101 when I measure the one you drew on the screen I
get A is 30 degrees C is 70 D is 80 You've made up 60 and 30
because that's what those angles look like. But remember D could
be anywhere on the circumference. I drew a circle and the first
half is 30, 30,
