Step-by-step explanation:
Standard equation of an ellipse,

(h, k) is the center of the ellipse
Value of a = Distance of the center from the vertex
b = Distance of the center from the covertex
From the picture attached,
a = Distance of the center (h, k) from the vertex (2, -2) = 3 units
b = Distance of the center (h, k) from the co-vertex (-1, 0) = 1 unit
Center of the ellipse (h, k) = (-1, -2)
the answer is 10. if you take the lcm of 5 and 2 you should get it.
To determine what the circumference is simply take the value of the diameter and multiply it to the value of Pi or 3.141....
C = Pi • d
C = (3.14)(10 cm)
C = 31.41 cm or 31.4 cm, rounded to the nearest tenth.
