Solve pi21pi20pi29

$$\pi 21 \pi 20 \pi 29$$

Evaluate

$$12180\pi ^{3}\approx 377656.449966052$$

Solution Steps

Multiply \pi and \pi to get \pi ^{2}.

$$\pi ^{2}\times 21\times 20\pi \times 29$$

To multiply powers of the same base, add their exponents. Add 2 and 1 to get 3.

$$\pi ^{3}\times 21\times 20\times 29$$

Multiply 21 and 20 to get 420.

$$\pi ^{3}\times 420\times 29$$

Multiply 420 and 29 to get 12180.

$$\pi ^{3}\times 12180$$
