Question

find the area of sector whose length of the arc is 64m and radius is 20m​

Answer 1

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.

Answer 2

Answer:

hope this will help you

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.
