Question

Question on circles. Thanks for any help.

Answer 1

okay

Answer 2

Just plug in the radius into the perimeter of a circle formula.

\(P = 2 \pi r\)

\(P = 2 (3.14) (2)\)

Simplify that

Answer 3

perimeter of this one is = 2r + length of arc

Answer 4

After we find this, then we can divide by 4.

Answer 5

igreen's idea is much simplier. ^_^

Answer 6

I got 3.14 again...

Answer 7

That's not right..

\(2 \times 3.14 \times 2 =~?\)

Answer 8

12.56

Answer 9

Yes, now divide by 4

Answer 10

Lol, yeah..3.14 :P

Answer 11

Yes, rounding will give us 3.1, so that's your answer.

Answer 12

Thanks! :)

Answer 13

@iGreen , i think you're wrong on this one.

Answer 14

@iGreen , you only gave the length of the arc on this one...

so the total perimeter of this figure is P= 2r+length of arc

Answer 15

still there @nevermind_justschool ?
