h=1.35
r = 12.5
V = ½x3.14xr2xh - 2/3xr2xh
Can someone figure out doing that one ?
Hello, Gundel!
h = 1.35, r = 12.5
$\displaystyle V \:= \:\frac{1}{2}\pi r^2h - \frac{2}{3}r^2h$
Can someone figure out doing that one ? . . . figure out what ?
Are you asking us to do your arithmetic for you?
Don't you have a calculator?
$\displaystyle V \;= \;\left(\frac{1}{2} \times \pi \times 12.5^2 \times 1.35\right) - \left(\frac{2}{3} \times 12.5^2 \times 1.35\right) $
