22/7×12×20+22/7×12×12
You asked:
Evaluate the expression: \(\frac{22}{7} \cdot 12 \cdot 20 + \frac{22}{7} \cdot 12 \cdot 12\)
MathBot Answer:
\[\frac{22}{7} \cdot 12 \cdot 20 + \frac{22}{7} \cdot 12 \cdot 12 = \frac{8448}{7} = 1206.\overline{857142}\]
\[\begin{aligned}\frac{22}{7} \cdot 12 \cdot 20 + \frac{22}{7} \cdot 12 \cdot 12& = \frac{264}{7} \cdot 20 + \frac{22}{7} \cdot 12 \cdot 12\\& = \frac{5280}{7} + \frac{22}{7} \cdot 12 \cdot 12\\& = \frac{5280}{7} + \frac{264}{7} \cdot 12\\& = \frac{5280}{7} + \frac{3168}{7}\\& = \frac{8448}{7}\end{aligned}\]
