Question

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

Answer 1

measure of arc QR = 28.8°

Explanation:

Full circle = 100% = 360°

Measure of arc QR = percentage covered by arc QR / 100 × 360

arc QR covers 8%

Therefore:

measure of arc QR = 8/100 × 360°

measure of arc QR = 0.08 × 360°

measure of arc QR = 28.8°
