Question

The degree measure of the circumference of the circle is always

• A. $0^{\circ }$
• B. ${90}^{\circ }$
• C. ${180}^{\circ }$
• D. ${360}^{\circ }$

Answer 1

Answer: (D)

${360}^{\circ }$

$\Rightarrow$ The degree measure for the circumference of a circle is ${360}^o$.

$\Rightarrow$ This is because the sum of total angles in a circle is ${360}^o$.

$\Rightarrow$ Whenever we want to get the length of an arc which is part of the circumference of a circle we will always refer to the total angle of a circle which is ${360}^o.$
