The circumference of the circle is = 2 x pi x 6 = 37.7cm
To find the arc = 360 divided by 169 = 2.13
The arc = 37.7 divided by 2.13 = 17.69 cm
Area for a circle is

. We will fill in each area and then solve for the radius.

and

. ∴

and r = 13. For b,

and

.

, ∴ r = 17. For c,

, and

. ∴,

and r = 11. For d,

, and

. ∴,

so r = 25. And there you have it!
