evaluating formulas i need help checking.

[vinceman]

v=3.14 (r sq.)h / v=235.5 and r=5

235.5=3.14(5 squared)h

235.5=3.14(10)h

235.5=31.4 (h)

235.5 - 31.4= 204.1

204.1=h

Is this right?

with the r^2 it should be 5 x 5 =25 not 10.

Try this step again

I am assuming (5 squared) = 5^2. In that case, (5 squared) ≠ 10. (5 squared) = 5(5) = 25.

if you get h =3 then you are on the right track with the maths.
