Solve 45pi/11*rd=pi/11

$$\frac { 45 \pi } { 11 } \cdot r d = \frac { \pi } { 11 }$$

Solve for d

$$d=\frac{1}{45r}$$

$$r\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 11.

$$45\pi rd=\pi$$

Divide both sides by 45\pi r.

$$\frac{45\pi rd}{45\pi r}=\frac{\pi }{45\pi r}$$

Dividing by 45\pi r undoes the multiplication by 45\pi r.

$$d=\frac{\pi }{45\pi r}$$

Divide \pi by 45\pi r.

$$d=\frac{1}{45r}$$

Solve for r

$$r=\frac{1}{45d}$$

$$d\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 11.

$$45\pi rd=\pi$$

Reorder the terms.

$$45\pi dr=\pi$$

Divide both sides by 45\pi d.

$$\frac{45\pi dr}{45\pi d}=\frac{\pi }{45\pi d}$$

Dividing by 45\pi d undoes the multiplication by 45\pi d.

$$r=\frac{\pi }{45\pi d}$$

Divide \pi by 45\pi d.

$$r=\frac{1}{45d}$$
