Question

What is the circumference of circle with diameter 7 cm?

Answer 1

Answer:21.99

Step-by-step explanation: Given diameter of a circle is(d)=7cm.

Now, we know that circumference of circle is =πd, where d is diameter of circle.

So, here circumference is = π×7cm

= 22/7 x 7 cm

Circumference = 22cm

Answer 2

$\sf \bf {\boxed {\mathbb {GIVEN:}}}$

Diameter of the circle "d" = 7 cm

$\sf \bf {\boxed {\mathbb {TO\:FIND:}}}$

The circumference of the circle.

$\sf \bf {\boxed {\mathbb {SOLUTION:}}}$

$\sf\orange{The\:circumference \:of\:the\:circle\:is\: 22\:cm.}$

$\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:EXPLANATION:}}}$

We know that,

$\sf\purple{Circumference\:of\:a\:circle \:=\:πd }$

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

$= 22 \: cm$

Therefore, the circumference of the circle is 22 cm.
