expand (pi/4-1/2)400

Solution

expand

(\frac{π}{4} - \frac{1}{2}) 400

Solution

100 π - 200

Solution steps

(\frac{π}{4} - \frac{1}{2}) \cdot 400

= 400 (\frac{π}{4} - \frac{1}{2})

Apply the distributive law:

a (b - c) = ab - a c

a = 400, b = \frac{π}{4}, c = \frac{1}{2}

= 400 \cdot \frac{π}{4} - 400 \cdot \frac{1}{2}

Simplify

400 \cdot \frac{π}{4} - 400 \cdot \frac{1}{2} : 100 π - 200

= 100 π - 200
