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

Let's assume

radius =r

The circumference of the great circle of a hemisphere is 19π inches

we know formula of circumference

now, we can plug C

now, we can solve for r

so, radius is 9.5 inches

now, we can find diameter

we know that

so, diameter is 19 inches

now, we can find surface area

now, we can plug r

so, surface area is 850.58621 inch^2

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
