Short Answer

Expert verified

The required Area of sector is25meter2.

Step by step solution

01

Step 1. Given information

r=10meters,胃=12radian,A=?

02

Step 2. Formula Used

The area Aof the sector of a circle of radius rformed by the central angle of 胃radians is

A=12r2胃

03

Step 3. Calculation

We have,

r=10meters,胃=12radian

Now,

The area A of a sector is

A=12r2胃

鈬�A=12脳102脳12

鈬�A=25metersquare
