Question

the volume of a large can of tuna fish can be calculated by using the formula V= *pi*r^2h. write an equation to find the radius,r, in terms of V and h

Answer 1

V= pi x r^2 x h

V/(pi x h)=r^2

square root of [V/(pixh)]=r

Answer 2

$V=\pi r^2h\\ r^2=\dfrac{V}{\pi h}\\ r=\sqrt{\dfrac{V}{\pi h}$
