Answer 1

I can’t see the option images you pasted. I can help as soon as you either upload them again or describe each choice.

Meanwhile: the given circle has diameter 20 so radius r = 10. Its area is
A = πr^2 = π(10)^2 = 100π ≈ 314.16.

So any figure whose area equals 100π is equivalent. A few convenient equivalents to look for in the choices:
- A square of side s where s^2 = 100π → s = 10√π ≈ 17.72.
- A rectangle 20 by 5π (20·5π = 100π).
- Any circle radius 10 (same as the given).
- A semicircle whose radius R satisfies (1/2)πR^2 = 100π → R = √200 ≈ 14.142.

If you repost or describe the four options I’ll pick the correct one.
