2.option 1

Explanation:

1.circumference of circle=2πr=2π×24=48π or 151in

2.circumference of circle=2πr

272.2=2πr

r=272.2/(2π)=43.3in

Answer 2

9514 1404 393

Answer:

1. (d) 151 in

2. (a) 43.3 in

Explanation:

1. The circumference is ...

C = 2πr

C = 2(3.14)(24 in) = 150.72 in

C ≈ 151 in

__

2. C = 2πr

r = C/(2π) = 272.2 in/(2·3.14) ≈ 43.3439 in

r ≈ 43.3 in
