What is the circumference

sleet_krkn [62]

Answer: 69.43 cm

Step-by-step explanation:

Given: Arc length (JK) = 40.5 cm

Central angle ∠ JLK = 210°

Arc length = $\dfrac{x}{360}\times\text{Circumference}$

$\Rightarrow\ 40.5=\dfrac{210}{360}\times\text{Circumference}\\\\\Rightarrow \text{Circumference} =40.5\times\dfrac{360}{210}\\\\\approx69.43\ cm$

Hence, Circumference = 69.43 cm
