Step-by-step explanation:
Length=48m.
Radius =10m.
circumference =2π(10)=10πm. Find the area:
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.
