Question

the area of sector which is 1/ 4 the area of circle of radius r units​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

The area of the sector is π r² / 4.

• We know that area of circle = π r² and area of the sector is Θ π r² / 360°.

• As per the question, the Area of the sector is = 1 / 4 area of the circle.

• Thus,

Θ π r² / 360° = π r²

Θ = 90°

• Now, area of sector = Θ π r² / 360°

                                 = 90 x π r² / 360°

                                 = π r² / 4
