In order to determine the are of the sector, use the following formula:


A=(\theta)/(360)\cdot\pi r^2

where,

θ = m

π = 3.14

r = DE = 3

replace the previous values of the parameters into the formula for A and simplify:


A=(36)/(360)\pi(3)^2\approx2.83

Hence, the area of the given sector is approximately 2.83 squared units
