The area of sector is 1.57 m²
<u>Explanation:</u>
Given:
Radius, r = 3 m
Central angle of a sector = 1/9π radians
Area of sector, A = ?
We know:
Area of sector, A = 
where,
α is the central angle in radians
On substituting the value we get:

Therefore, the area of sector is 1.57 m²
Answer:
We obtain same product by both the methods.
Step-by-step explanation:
We are given the following in the question:
Commutative property of multiplication:

Different ways to find the product:
1. First way

2. Second way
