Question

the circumference of a circle with radius 3.5 cm and Centre 22 cm find the perimeter of the quarter of the circle​

Answer 1

Answer:

Radius=3.5

Step-by-step explanation:

circumference of circle = 2πr

= 2×22/7 × 35/10

=22 cm

Now, perimeter of quadrant of a circle= theta/360 ×2πr

=90°/360°× 22

=1/4 × 22

=11/2 cm²
