Answer:
Step-by-step explanation:
r = 9.1 m
SA =3πr²

B>a
<span>b=3a-22, b+2a=98, using b from the left in the right: </span>
<span>3a-22+2a=98 </span>
<span>5a-22=98 </span>
<span>5a=120 </span>
<span>a=24, and since b=3a-22, </span>
<span>b=50 </span>
<span>So the smaller number is 24 and the larger number is 50.</span>
