Radius
is half of the circle
diameter
is the whole thing inside the circle
since it is a radius, and it is a half of the full circle, we need to double out that number, and multiply by 2.
so here, you said it is 28
take 28, and multiply by 2, if you do every thing correctly, you should get:
56
so then answer would be 56 centimeters.
Hope that this helps you! =)

Describe how to construct an angle bisector with a compass and starightedge.

Nina [5.8K]

Here is how to bisect the angle B A C: Place the point of the compass on A, and swing an arc E D. Then, with D as center and D E as radius, draw an arc. Keeping the same radius and with E as center, draw an arc that will intersect the first; call that point of intersection F, and draw A F.
