Question

find the circumference of a circle, if r= 28 m

Answer 1

HI,
=======================
Circumference of a circle = 2*$\pi$* r

Given that, r=28m

∴ 2 * $\frac{22}{7}$ *28 = 176m                    [Took $\pi$ as 22/7 ]
Answer
===================
Hope you are helped :-)

Answer 2

hey friend...

herez ur answer...


As we know to find the circumference of a circle , we use the formula

$2 \times pie \times radius$
and as we have that radius is 28 , we don't have much work.

circumference =
$2 \times \frac{22}{7} \times 28$

$2 \times 22 \times 4$

$44 \times 4$

$176$

circumference is 176 cm
