PLEASE HURRY!! CIRCUMFERENCE AND PIRIMITER APPLICATIONS question Don't mind the answer I put I didn't mean to click it... thank you!!​

Answer 1

Option C:

Perimeter of the $\frac{1}{4}$ of a circle = 10.71 cm

Solution:

Given figure is  $\frac{1}{4}$ of a circle.

It is a quarter of a circle.

Radius = 3 cm, Value of π = 3.14

To find the perimeter of the quarter of a circle.

Perimeter of the quarter of a circle formula: $\frac{\pi r}{2}+2r$

$\text {Perimeter} =\frac{\pi r}{2}+2r$

               $=\frac{3.14\times3}{2}+2\times3$

               $=4.71+6$

               $=10.71$

Perimeter of the quarter of a circle = 10.71 cm

Option C: 10.7 is the correct answer.

Hence perimeter of the $\frac{1}{4}$ of a circle is 10.71 cm.
