Question

Find the circumference of a circle whose diameter is 28 cm.​

Answer 1

Step-by-step explanation:

d=28cm

r=14cm

Circumference=2πr

= 2× 22/7×14

= 2×22×2

=4×22

=88cm

Answer 2

$= = = = = = = = = = = = = = = = = = = = = = = = = =$

$solution :$

$diameter \: of \: circle \: = 28cm$

$thus \: cirumference \: = \pi \times 28 \: cm$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{22}{7} \times 28 \: cm$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 22 \times 4cm$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 88cm$

$hence \: required \: answer \: is \: 88 \: cm$

$= = = = = = = = = = = = = = = = = = = = = = = = = =$
