Question

find the circumference of a circle whose diameter is 84cm ​

Answer 1

Step-by-step explanation:

$circumference \: of \: circle = 2\pi \times r$

d=2r

r=84/2=42

circumference=2*22/7*42=84*22/7

=22*12=264cm.

Answer 2

☆ANSWER☆

Radius = Diameter ÷ 2

= 84 ÷ 2

= 42cm

Circumference of circle

= 2 x pi x r

= 2 × 22/7 × 42

= 2 × 22 × 6

= 44 × 6

= 264 cm.
