Answer:

Orbital speed is given by the formula:

v=\sqrt{\frac{GM}{r}}

Mass of Ceres, M = 1.98\times 10^{30} kg

The closest distance of Ceres to sun is : 382,620,000,000 m

orbital speed of Ceres at perihelion is:

v=\sqrt{\frac{1.67\times 10^{-11}\times 1.98\times 10^{30}}{382,620,000,000}} = 9296.23 m/s =20795.07 miles/hour

The farthest distance of Ceres to sun is : 382,620,000,000 m

orbital speed of Ceres at aphelion is: 414,010,000,000 m

v=\sqrt{\frac{1.67\times 10^{-11}\times 1.98\times 10^{30}}{414,010,000,000}} = 8936.87 m/s = 19991.2 miles/hour

When the height increases up to its maximum length, then secondary growth begins which add tissues to the side that is it increases the girth by adding bark, secondary xylem and phloem.

Thus, Height and Girth is correct.
