Solve 13*(pi*(9*2))+(pi9^2*2)

$$13 \times ( \pi \times (9 \times 2))+( \pi { 9 }^{ 2 } \times 2)$$

Evaluate

$$396\pi \approx 1244.070690822$$

Solution Steps

Multiply 13 and 9 to get 117.

$$117\pi \times 2+\pi \times 9^{2}\times 2$$

Multiply 117 and 2 to get 234.

$$234\pi +\pi \times 9^{2}\times 2$$

Calculate 9 to the power of 2 and get 81.

$$234\pi +\pi \times 81\times 2$$

Multiply 81 and 2 to get 162.

$$234\pi +\pi \times 162$$

Combine 234\pi and \pi \times 162 to get 396\pi .

$$396\pi$$
