Question

The circumference of a circle is $28.08\text{cm}$. Find length of minor arc of the circle if length of major arc of the circle is $24.08\text{cm}$.

• A. $3$ cm
• B. $4$ cm
• C. $3.51$ cm
• D. $7.02$ cm

Answer 1

The correct option is B $4$ cm

We know:
Length of minor arc of the circle + Length of major arc of the circle = Circumference of the circle.

Where,
$24.08\text{cm}=\text{length of major arc of the centre}$
$28.08\text{cm}=\text{circumference of the circle}$.

Hence, Length of minor arc of the circle $=28.08-24.08=4\text{cm}$


Hence, option $\left(b\right)$ correct.
