Question

find the area of the sector whose length of the arc (L) is 48m and radius (r) is 10m​

Answer 1

SOLUTION:

GIVEN,

Length=48m.

Radius =10m.

Find tha circumference

circumference =2πr

circumference =2π(10)=10πm.

Find the area:

Area = πr²

Area = π(10)^2=100πm^2.

Find the area of the sector:

Arc Length = 48m

Area of the sector = ( arc length / Circumference ) x Area.

Area of the sector =(48m/10πm)×100πm^2

=480m^2

Hence the area of sector is 480m^2
