Question

A soda can has a diameter of 6 cm. What is the circumference of the can? (C = πD)

Answer 1

given :
Diameter = 6cm
$radius = \frac{diameter}{2}$

$= \frac{6}{2} = 3$



we know that :
circumference =2πr
so
$2 \times \pi \times 3$
= 6π
or
$6 \times \frac{22}{7} = 18.85$

therefore Circumference (c) = 18.85 cm
