Question

Let's divide a circle into $10$ equal parts. Then, the measure of each central angle of a circle is :

• A. ${18}^o$
• B. ${72}^o$
• C. ${36}^o$
• D. ${30}^o$

Answer 1

The correct option is C ${36}^o$

Since, circle divides in 10 equal parts, total measure angle at centre $=360°$.

So, each central angle after division is $=\frac{360°}{10}=36°$
