Solve 3.14*(46.8^2-40^2)*2

$$3.14 \times ( { 46.8 }^{ 2 } - { 40 }^{ 2 } ) \times 2$$

Evaluate

$$3706.7072$$

Solution Steps

Calculate 46.8 to the power of 2 and get 2190.24.

$$3.14\left(2190.24-40^{2}\right)\times 2$$

Calculate 40 to the power of 2 and get 1600.

$$3.14\left(2190.24-1600\right)\times 2$$

Subtract 1600 from 2190.24 to get 590.24.

$$3.14\times 590.24\times 2$$

Multiply 3.14 and 590.24 to get 1853.3536.

$$1853.3536\times 2$$

Multiply 1853.3536 and 2 to get 3706.7072.

$$3706.7072$$

Factor

$$\frac{7 \cdot 17 \cdot 31 \cdot 157 \cdot 2 ^ {2}}{5 ^ {4}} = 3706\frac{442}{625} = 3706.7072$$
