Question

Find the circumference of the circle of 3 cm

Answer 1

circumference of circle is 2pie r = 2 × 22/7 × 3 = 18.85 ....

hope its helps ...

Answer 2

◾◾The circumference of a circle is equal to the pi ¶¶ times the diameter d . ◾◾
$\pi \times diameter$

◾since the diameter d is equal to the two times the radius r.

⚫the formula for circumference using radius is 2¶¶r.
$2\pi \times radius$

◾Substitute the value of the radius ( r = 3 cm)
into the formula for the area of a circle .
Pi ¶¶ is. approximately equal to 3.14 .
$3.14 \times 2 \times (3cm)$

◾Multiply 3.14 by 2
$6.28 \times (3cm)$

⚫ Multiply 6.28 by 3cm.
$6.28 \times 3cm$

⚫. Multiply 3 by 6.28
$18.84cm.$

$hence \: the \: \: circumference \: \\ of \: circle \: is \: 18.84cm.$

$be \: brainly.$
