​how many meters is the circumference of a circle with a radius of 20 cm?
Harman [31]
First find the circumference of the circle.
Circumference: 2 \pi r

Plug in 20 for the radius (r).
2 \pi20 = 125.66 

The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.

Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26

The circle's circumference is 1.26 meters.

Please help I am so confused lol. I’ll mark you the brainiest
ANTONII [103]

Answer:

Since the pentagon is regular, the line connecting the centre of the circle to the verticles (A,B,C,D,E) should inscribe an equal angle in them

You can see what I mean in the attachment

So to mark other points we follow the following steps

  1. Connect OA
  2. With OA as base, make angle of 72°. Say th new line is OB.
  3. Similarly, do for the rest of them
  4. This is a cyclic pentagon

Step-by-step explanation:
