HELPPPPP!! The formula gives the volume V of a right cylinder with radius r and height h.

V=πr²h Solve for r.

Explain your answer. Should either answer be discarded? Why or why not?

Respuesta :

Answer:

see explanation

Step-by-step explanation:

Isolate r² by dividing both sides by πh

r² = [tex]\frac{V}{h\pi }[/tex]

Take the square root of both sides

r = ± [tex]\sqrt{\frac{V}{h\pi } }[/tex]

The negative part can be  discarded as r > 0, hence

r = [tex]\sqrt{\frac{V}{h\pi } }[/tex]
