Question

we have a field in the shape of a a sector of a circle,the central angel of the field is 15 degree and the radius of the circle is 321m.find the area of the field.

Answer 1

a sector is a ratio of a full circle

Answer 2

ie 321^2*pi*15/360

Answer 3

does that make sense?

Answer 4

321^2*pi=full circle
15 degrees/360 degrees is the ratio

Answer 5

then 1/3(15/360)(321^2) will give you the answer.
