Answer:
0.12 m
0
Explanation:
d = diameter of the circle = 24 cm = 0.24 m
r = radius of the circle
radius of the circle is given as
r = (0.5) d
r = (0.5) (0.24)
r = 0.12 m
L = length of the semi-major axis
For a circle, we know that
length of the semi-major axis = Radius of the circle
L = r
L = 0.12 m
Also for a circle , we know that eccentricity is 0
so e = 0
