Question

If the circumference of a circle with radius 3.5 cm and centre O is 22 cm find the perimeter of the quarter of the circle

Answer 1

perimeter of quarter of the circle
= (2×radius) + (circumference/4)
= (2×3.5) + (22/4)
=7+5.5
=12.5 cm

I hope this helps you..

Answer 2

Answer:

Perimeter of the quarter circle is 12.5 cm.

Step-by-step explanation:

Given : If the circumference of a circle with radius 3.5 cm and center O is 22 cm.

To find : The perimeter of the quarter of the circle?

Solution :

Circumference of circle C= 22 cm  

Radius r=3.5 cm

Quarter= 1/4th of circle  

Perimeter of quarter of the circle  is

$P=2r+\frac{C}{4}$

$P=2\times 3.5+\frac{22}{4}$

$P=7+5.5$

$P=12.5$

Therefore, Perimeter of the quarter circle is 12.5 cm.
