Solve 2*pi*11^2+2*pi*11*145

$$2 \times \pi \times { 11 }^{ 2 } +2 \times \pi \times 11 \times 145$$

Evaluate

$$3432\pi \approx 10781.94598712$$

Solution Steps

Calculate 11 to the power of 2 and get 121.

$$2\pi \times 121+2\pi \times 11\times 145$$

Multiply 2 and 121 to get 242.

$$242\pi +2\pi \times 11\times 145$$

Multiply 2 and 11 to get 22.

$$242\pi +22\pi \times 145$$

Multiply 22 and 145 to get 3190.

$$242\pi +3190\pi$$

Combine 242\pi and 3190\pi to get 3432\pi .

$$3432\pi$$
