Data collected in a survey shows that 40% of the buyers are interested in buying a particular brand of toothpaste. The central angle of the sector of the pie chart representing this information is

We know that,

Central angle of the pie chart = 360°


Buyers interested in buying a particular brand of toothpaste = 40%


Central angle of the sector = 40% of Central angle of the pie chart


⇒ Central angle of the sector = 40% of 360°



⇒ Central angle of the sector = 144°


Hence, the central angle of the sector of the pie chart representing this information is 144°.
