4 0

Find the length of the circumference:

Circumference = 2 x pi x radius

Circumference = 2 x 3.14 x 7

Circumference = 43.96 kilometers

90 degrees is 1/4 of a circle ( 360/4 = 90)

Arc length = 43.96/4 = 10.99 kilometers

(Round answer as needed)

288 = 2x^2

144 = x^2

x = 12 or x = -12, but the latter is nonsensical.
