Question

formula for perimeter of quadrant

Answer 1

Answer:

π(r)/2+2r

circumference/perimeter of circle=2πr

quadrant=1/4 of circle

hence

perimeter of quadrant = πr/2+2r

Answer 2

The perimeter of quadrant is $\frac{\pi r}{2} +2r$.

Given:

Quadrant of a circle

To Find: Perimeter of quadrant

Calculation:

• Perimeter of a circle = 2πr, where r is the radius of circle.
• When a circle is divided into 4 equal parts along the diameter, each part called a quadrant.
• Perimeter of quadrant is = 2r + (perimeter of circle)/4
• Perimeter of quadrant = 2r + (πr)/2

Answer:

Perimeter of quadrant = 2r + (πr)/2
