Answer:
1. (d) 151 in
2. (a) 43.3 in
Step-by-step 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
1.Option 4
2.option 1
1.circumference of circle=2πr=2π×24=48π or 151in
2.circumference of circle=2πr
272.2=2πr
r=272.2/(2π)=43.3in
