Question

As per the pie chart, the central angle of which of the following colors is ${126}^{\circ }$?

• A. Blue
• B. Red
• C. Green
• D. Yellow

Answer 1

The correct option is C Green

Since the central angle of a sector in a pie chart is directly proportional to its percentage share, we have ${360}^{\circ }:100\%::{126}^{\circ }:x$
Thus, $x=100\%\times \frac{{126}^{\circ }}{{360}^{\circ }}=35\%$, which corresponds to Green.
