Question

Calculate the area and perimeter of sectorwith radii 60 cm and angle between
them is 270° ( use = 3.14)
​

Answer 1

Answer:

Perimeter is the total length of the shape.

A sector in a circle is made up of two radii and one arc.

length of the radii= 2×r=2×14=28cm

length of the arc= rθ

Given θ=60

∘

=π/3radians

Length of the arc= rθ=14×π/3=44/3cm

Total length=28+14.67=42.67cm
