Attached the solution and work. The x,y,n are just variables I put in so you could see how I solved for the missing angle.
The formula for volume of a sphere is 4/3pi(radius)^3
So 4/3(3.14 - better to use the pi button on your calculator)(4 cubed)
Punch into calculator (And I mean PUNCH that thing)
Volume = 268.08 in.^3. Divide this by 2.5 = 107.23 seconds.
Answer:
X+20=2 i think this is a little above my head
4 is correct
reason is because the number next to x is the constant number and the end number is where you started
