Question

1. if the circumference of the circle is equal to 72 cm, find the length of the solid arc. arc length = \boxed{} cm

Explanation:

Step1: Recall arc length formula

Arc length = $\frac{\theta}{360^\circ} \times$ Circumference, where $\theta=140^\circ$

Step2: Substitute values

Arc length = $\frac{140}{360} \times 72$

Step3: Calculate the result

$\frac{140}{360} \times 72 = 140 \times \frac{72}{360} = 140 \times 0.2 = 28$

Answer:

28 cm
