Question

In a pie chart if a sector for two wheelers shows 40% of the total vehicles,then find the measure of central angle for the sector showing two wheelers

Answer 1

Answer:

144°

Step-by-step explanation:

Share of two-wheelers = 40% = 0.4

Sector angle for two-wheelers = 0.4*360 = 144

The angle of a category is the share of that category expressed with respect to 360°.

If share is 40%, angle is 40% of 360 (which is 144)

Answer 2

Answer:

Central angle for cars is given by,

⇒

⇒ Central angle for cars = 108°

Thus, central angle for cars is 108°.

Step-by-step explanation:

To find central angle for tempos:

Given that, percentage of tempos passing a signal in a town = 12%

⇒ Number of tempos = 12

& Total number of vehicles = 100

Central angle for tempos is given by,
