circumference = 2 x pi x r
56 = 2 x 3.14 x r
56 = 6.28 x r
r = 56/6.2
r = 8. 917
d = 8.917*2 = 17.8
diameter = 18 meters
You want it to be greater than and equal to 2. A closed circle means to include 2 so you want a closed circle and to the right is to bigger numbers so you want to the right. So the answer is b. Number line with closed circle on 2 and shading to the right.
66/25 as a decimal would be 2.64.
