Question

Find the circumference of a circle whose Diameter is 26cm.

Answer 1

Answer:

81.71 cm or 81.64 cm

Step-by-step explanation:

Circumference = 2πr

diameter = 26 cm

radius = 26/2 = 13cm

If π = 22/7

Circumference = 2×22/7×13

= 572/7

= 81.71 cm

If π = 3.14

Circumference = 2×3.14×13

= 81.64 cm

Anyways the answer will be approximately 81.5cm

Hope it helps..

Thank you..

Answer 2

Answer:

Diameter = 26cm

Radius =Diameter ÷ 2

=26 ÷ 2

Radius =13cm

circumstances of a circle = 2πr

= 2×3.14×13

=6.28×13

= 81.64cm

Therefore, circumstances of the circle is 81.64cm
