Can someone help me with this?

36000pi

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

We know the surface area

SA = 4 pi r^2

3600 pi = 4 pi r^2

Divide each side by 4pi

3600 pi / 4pi= 4 pi r^2/4pi

900= r^2

Take the square root of each side

30 = r

Now substitute into the equation for volume

V = 4/3 pi r^3

   = 4/3(pi) (30)^3

    =36000pi

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
