The circumference of the great circle of a hemisphere is 19π inches. which statements about the hemisphere are true? check all that apply. (use 3.14 for π and round answers to the nearest tenth, if necessary. recall that the formula for the surface area of a hemisphere is s = 3πr2 and the formula for the circumference of the great circle is c = πd.) the radius of the hemisphere is 9.5 inches. the radius of the hemisphere is 19 inches. the surface area of the hemisphere is 3,400.6 square inches. the surface area of the hemisphere is 850.2 square inches. the diameter of the hemisphere is 9.5 inches. the diameter of the hemisphere is 19 inches
