Question

The measure of an arc of a circle is 80° cm and its radius is 18 cm. Find the length of the arc. ( \[\pi\]  = 3.14 )

Solution

Radius of the arc, r = 18 cm
Measure of the arc, θ = 80º
∴ Length of the arc = \[\frac{\theta}{360° } \times 2\pi r = \frac{80°}{360°} \times 2 \times 3 . 14 \times 18\] = 25.12 cm

Thus, the length of the arc is 25.12 cm.

  Is there an error in this question or solution?
