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

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
