Question

A plot of land is in the shape of sector of circle of radius 28m. If centre angle is 60 degree, find area and perimeter of their plot.

Answer 1

123*567 (67-89) * 0+3= ?

Answer 2

Answer:

Step-by-step explanation:

The formula for the Area is given by:

Area of a sector = Ф/360 × π × r²

Where Ф = Angle subtended at the center.

We do the substitution as follows:

= 60/360 × π × r^2

60/360 × 3.142 × 28 × 28 = 410.55 square meters

That gives the area of the sector.

We now need the length of the arc or rather the perimeter.

Perimeter :

Perimeter = Ф/360 × π × 2r

Doing the substitution we have :

= 60/360 × 3.142 × (28 × 2)

This gives us :

= 29.33 m
