Question

i need help look at attachment plz!!!!!

Answer 1

the 80 degrees is supposed to br in between f and g

Answer 2

This is essentially the same problem. Just with different numbers. What have you tried to solve it?

Answer 3

i dont know where to start

Answer 4

What is the arc length for a portion of a circle described by an angle?

Answer 5

is it 7m?

Answer 6

No, in general. If you have a circle with radius r, what is the length of the arc described by the angle Theta?

Answer 7

johnlajoie, something is not correct with the diagram

Answer 8

here

Answer 9

this is the rite one

Answer 10

No, that diagram is wrong. It claims there is a D which should give some information about the size of the radius. But it's not shown in the drawing.

Answer 11

my bad got it now

Answer 12

So again. Given how is the radius, angle and arclength of a portion of a circle related?

Answer 13

I guess that H, not N. And question 3 should be length of EFG and not FEG

Answer 14

nope its FEG

Answer 15

they all r requred to solve the problem

Answer 16

is dat correct?

Answer 17

Can you tell me how an angle, radius and arclength are related? If you can figure this out (look in your book) it should give you some idea where to start.

Answer 18

can u help me with numbers 1-3 pls step by step??

Answer 19

Yes, but first you have to answer my question. I'm certain that this info was covered by your teacher, in your book, and in the previous question you asked about this subject.

Answer 20

Given a radius and an angle(in radians) how do you find the arclength subtended by that angle?

Answer 21

the arc length = measure of central angle in radians x radius length

Answer 22

Correct. And your diagram is still wrong. It doesn't have an H even though the question asks for it, D is not a diameter, and No info is given about how H relates to the other points.

Answer 23

this is the last thing it could be
