Solve 628.32=(pi8^2)+x(pi16)

$$628.32 = ( \pi 8 ^ { 2 } ) + x ( \pi 16 )$$

Solve for x

$$x=\frac{3927}{100\pi }-4\approx 8.50002923$$

Steps for Solving Linear Equation

Calculate 8 to the power of 2 and get 64.

$$628.32=\pi \times 64+x\pi \times 16$$

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

$$\pi \times 64+x\pi \times 16=628.32$$

Subtract \pi \times 64 from both sides.

$$x\pi \times 16=628.32-\pi \times 64$$

Multiply -1 and 64 to get -64.

$$x\pi \times 16=628.32-64\pi$$

The equation is in standard form.

$$16\pi x=628.32-64\pi$$

Divide both sides by 16\pi .

$$\frac{16\pi x}{16\pi }=\frac{628.32-64\pi }{16\pi }$$

Dividing by 16\pi undoes the multiplication by 16\pi .

$$x=\frac{628.32-64\pi }{16\pi }$$

Divide 628.32-64\pi by 16\pi .

$$x=\frac{3927}{100\pi }-4$$
