Question

The circle graph shows the distribution of age groups of people living in a city. Identify the measure of arc PR. HELP ASAP!!

Answer 1

100.8°

Explanation:

∠POR = ∠POQ + ∠QOR

∠POQ is 20% of 360° ( measure of the angles in a circle )

= 0.2 × 360° = 72°

∠QOR is 8% of 360° = 0.08 × 360° = 28.8°

Hence

arc PR = ∠POR = 72° + 28.8° = 100.8°
