C. 45.82

Step-by-step explanation:

We know the circumference is given by

C = 2 * pi *r

24 = 2 * 3.14 * r

24 = 6.28r

Divide each side by 6.28

24/6.28 = r

r = 3.821656051

We want to find the area

A = pi r^2

A =3.14 * (3.821656051) ^2

=45.85987261

All this requires is some distribution and combining of termsso.. $1.)$ $4.5(8 - x) + 36 = 102 - 2.5(3x + 24)$ $36 - 4.5x = 102 - 7.5x + 60$ $3x = 126$ $x = 42$ $2.)$ $12x > 9(2x - 3) - 15$ $12x > 18x - 27 - 15$ $42 > 6x$ $7 > x$ $x < 7$
