To find:

The exact area of the 1350 sector shown in the figure.

Explanation

Given:

Find the exact area of the 1350 sector shown.

Theorem:

In a circle of radius length r, the area A of a sector whose arc has degree measure m is given by A=m360πr2.

From the given, r=12 cm, and m=135.

To find the area of the sector, substitute r=12, and m=135 in A=m360πr2

A=135
