Answer:
see below
Step-by-step explanation:
1). 8 radii are shown, there are 8 straight lines going from the center of the circle to the edge of the circle
2) diameter = d, radius = r. given radius r ,
d = 2r
d = 2(14.5) = 29
the diameter is 29 cm
3)using d = 2r
7x+5 = 2(13) = 26
7x = 21
x = 3
4)the length of the diameter is increased 3 times
d1 = 2r,
d2 = 2(3r) = 6r
we see that the diameter whose radius is 3 times longer is 3 times larger than the diameter whose radius is 1 times as long.
5) they can find the diameter of the circular path, then find the radius, go from one point on the circular path and go r distance
