Me answer part (iii) in the photo.

must show step by step guide to how you got your answers☺

A.) v = πr^2h
v = π (20^2) * 50
v = π (400*50)
v = 20,000π

B.) v = πr^2h
v = π (4^2) * 10
v = π (16*10)
v = 160π

C.) 20,000π ÷ 160π = 125π
So, it can fill 125 mugs.

The solution to the system of equations (-2,2)
