Solve pix(60/2)^2*20*2=

$$\pi x ( \frac { 60 } { 2 } ) ^ { 2 } \times 20 \times 2 =$$

Evaluate

$$36000\pi x$$

Solution Steps

Divide 60 by 2 to get 30.

$$\pi x\times 30^{2}\times 20\times 2$$

Calculate 30 to the power of 2 and get 900.

$$\pi x\times 900\times 20\times 2$$

Multiply 900 and 20 to get 18000.

$$\pi x\times 18000\times 2$$

Multiply 18000 and 2 to get 36000.

$$\pi x\times 36000$$

Differentiate w.r.t. x

$$36000\pi$$
