Equations

Find: Vt (Total Volume)

Vt = (1/2)V1 + (1/2)(V2)

Vt = (1/2)(V1 + V2)                 [Factor out (4/3) and (pi) from volumes]

Vt = (1/2)(4/3)(pi)(R^3 + r^3)  [Sub in Values]

Vt = 4071.5 ft^3

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
