  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

Step-by-step 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

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
