This figure is 14 of a circle.

what is the best approximation for the perimeter of the figure?

use 3.14 to approximate pi.

4.7 cm
7.7 cm
10.7 cm
18.8 cm

18.8cm

Step-by-step explanation:

Multiply 3 by pi.

You get 9.42

Multiply that by 2.

You get 18.84.

Because the perimiter is also known as the circumference and the formula for that is 2rπ

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

answer: .75 km
