What is the best approximation for the perimeter of a semicircle with a diameter of 35 inches?
use 3.14 to approximate pi.
54.95 in.
89.95 in.
109.90 in.
144.90 in.

Perimeter (P) = 2 · π · r

Semi-perimeter = Perimeter : 2

[2 * 3.14 * (35 : 2)] : 2 =

= 54.95 in

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
