Solve SA=2pi(3.91)(7.82)+2pi(3.91)^2

$$S A = 2 \pi ( 3.91 ) ( 7.82 ) + 2 \pi ( 3.91 ) ^ { 2 }$$

Solve for A

$$A=\frac{458643\pi }{5000S}$$

$$S\neq 0$$

Steps for Solving Linear Equation

Multiply 2 and 3.91 to get 7.82.

$$SA=7.82\pi \times 7.82+2\pi \times 3.91^{2}$$

Multiply 7.82 and 7.82 to get 61.1524.

$$SA=61.1524\pi +2\pi \times 3.91^{2}$$

Calculate 3.91 to the power of 2 and get 15.2881.

$$SA=61.1524\pi +2\pi \times 15.2881$$

Multiply 2 and 15.2881 to get 30.5762.

$$SA=61.1524\pi +30.5762\pi$$

Combine 61.1524\pi and 30.5762\pi to get 91.7286\pi .

$$SA=91.7286\pi$$

The equation is in standard form.

$$SA=\frac{458643\pi }{5000}$$

Divide both sides by S.

$$\frac{SA}{S}=\frac{458643\pi }{5000S}$$

Dividing by S undoes the multiplication by S.

$$A=\frac{458643\pi }{5000S}$$

Solve for S

$$S=\frac{458643\pi }{5000A}$$

$$A\neq 0$$

Steps for Solving Linear Equation

Multiply 2 and 3.91 to get 7.82.

$$SA=7.82\pi \times 7.82+2\pi \times 3.91^{2}$$

Multiply 7.82 and 7.82 to get 61.1524.

$$SA=61.1524\pi +2\pi \times 3.91^{2}$$

Calculate 3.91 to the power of 2 and get 15.2881.

$$SA=61.1524\pi +2\pi \times 15.2881$$

Multiply 2 and 15.2881 to get 30.5762.

$$SA=61.1524\pi +30.5762\pi$$

Combine 61.1524\pi and 30.5762\pi to get 91.7286\pi .

$$SA=91.7286\pi$$

The equation is in standard form.

$$AS=\frac{458643\pi }{5000}$$

Divide both sides by A.

$$\frac{AS}{A}=\frac{458643\pi }{5000A}$$

Dividing by A undoes the multiplication by A.

$$S=\frac{458643\pi }{5000A}$$
