Question

A sector of a circle has a central angle of 135°. Find the area of the sector if the radius of the circle is 8 ft.

Answer 1

Remember that the area of a circle is \[A = \pi r ^{2}\]

Answer 2

Using that formula and diagram see if you can calculate the area of sector of the circle.

Answer 3

Hint: the area of the sector is ( 135 / 360 )th of the total area of this circle of radius 8 ft.

Answer 4

I wish back in school, that I got introduced to this formula in this method.Instead my teacher told to remember it as a formula :/ There's always a nice way of doing it!
