Question

A plot of land is in the shape of a sector of a circle 28m.If the sectorial angle (central angle) is 60 degrees , then find the area and the perimeter of the plot​

Answer 1

Answer:

The formula for the Area is given by:

...

<

Area of a sector = 0/360 × x r² X Where = Angle subtended at the

center.

We do the substitution as follows: = 60/360 x πT x r^2

60/360 × 3.142 x 28 x 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 = 0/360 x TTX 2r

Doing the substitution we have :

= 60/360 × 3.142 × (28 × 2) X

This gives us :

= 29.33 m
