Solve tautau*(18m)^2

$$\tau \tau \cdot ( 18 m ) ^ { 2 }$$

Evaluate

$$1296\left(\pi m\right)^{2}$$

Solution Steps

Substitute 2 * \pi for \tau.

$$2 * \pi 2 * \pi \cdot {(18 m)} ^ {2}$$

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

$$2\pi ^{2}\times 2\times \left(18m\right)^{2}$$

Multiply 2 and 2 to get 4.

$$4\pi ^{2}\times \left(18m\right)^{2}$$

Expand \left(18m\right)^{2}.

$$4\pi ^{2}\times 18^{2}m^{2}$$

Calculate 18 to the power of 2 and get 324.

$$4\pi ^{2}\times 324m^{2}$$

Multiply 4 and 324 to get 1296.

$$1296\pi ^{2}m^{2}$$

Expand

$$1296\left(\pi m\right)^{2}$$

Solution Steps

Substitute 2 * \pi for \tau.

$$2 * \pi 2 * \pi \cdot {(18 m)} ^ {2}$$

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

$$2\pi ^{2}\times 2\times \left(18m\right)^{2}$$

Multiply 2 and 2 to get 4.

$$4\pi ^{2}\times \left(18m\right)^{2}$$

Expand \left(18m\right)^{2}.

$$4\pi ^{2}\times 18^{2}m^{2}$$

Calculate 18 to the power of 2 and get 324.

$$4\pi ^{2}\times 324m^{2}$$

Multiply 4 and 324 to get 1296.

$$1296\pi ^{2}m^{2}$$
