Answer:

Step-by-step explanation:

Please be explicit in labeling the radius.   I will assume y ou meant r = 13 m.

Circumference formula:  C  = 2πr; area formula:  A = πr²

Here, with r = 13 m, C = 2π(13 m) = 26π m = C = 81.68 m

and

with r = 13 m, A = π(13 m)^2 = 169π = A = 530.93 m^2

7nadin3 [17]

Answer:

x>−6

Step-by-step explanation:

-6x<36

Multiply both sides by -1. ( reverse the inequality )

(-6x) (-1) > 36 (-1)

Simplify

6x > -36

Divide both sides by 6

6x divided by 6        -36 divided by 6

Simplify

x> -6
