Question

the perimeter of a circle of diameter 10 centimetre is​

Answer 1

Step-by-step explanation:

Given, diameter of circle(d) = 10cm

•°• Radius(r) of circle = d/2

= 10/2 = 5cm

==> Perimeter of circle= Circumference of circle

= 2πr

= 2×22/7 × 5 cm

= 31.43cm( approx.)

Thus the perimeter of circle is 31.43 cm.
