Solve 10000-2pi(25)^2=2pi(25)n

$$10000 - 2 \pi ( 25 ) ^ { 2 } = 2 \pi ( 25 ) n$$

Solve for n

$$n=\frac{200}{\pi }-25\approx 38.661977237$$

Steps for Solving Linear Equation

Calculate 25 to the power of 2 and get 625.

$$10000-2\pi \times 625=2\pi \times 25n$$

Multiply 2 and 625 to get 1250.

$$10000-1250\pi =2\pi \times 25n$$

Multiply 2 and 25 to get 50.

$$10000-1250\pi =50\pi n$$

Swap sides so that all variable terms are on the left hand side.

$$50\pi n=10000-1250\pi$$

Divide both sides by 50\pi .

$$\frac{50\pi n}{50\pi }=\frac{10000-1250\pi }{50\pi }$$

Dividing by 50\pi undoes the multiplication by 50\pi .

$$n=\frac{10000-1250\pi }{50\pi }$$

Divide 10000-1250\pi by 50\pi .

$$n=\frac{200}{\pi }-25$$
