In a year group of 216 students, 15 of them
achieved 90% or above in their maths test.
What angle would represent these 15 students
on a pie chart?

24.84°

Step-by-step explanation:

15 / 216 = 0.069 x  100 = 6.9%

6.9% of 360 degrees is 24.84°

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
