245-\frac{2\times 21}{3}\pi =\pi \times 14h
Express \frac{2}{3}\times 21 as a single fraction.
245-\frac{42}{3}\pi =\pi \times 14h
Multiply 2 and 21 to get 42.
245-14\pi =\pi \times 14h
Divide 42 by 3 to get 14.
\pi \times 14h=245-14\pi
Swap sides so that all variable terms are on the left hand side.
14\pi h=245-14\pi
The equation is in standard form.
\frac{14\pi h}{14\pi }=\frac{245-14\pi }{14\pi }
Divide both sides by 14\pi .
h=\frac{245-14\pi }{14\pi }
Dividing by 14\pi undoes the multiplication by 14\pi .
h=\frac{35}{2\pi }-1
Divide 245-14\pi by 14\pi .
