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
[tex]\sf \bf {\boxed {\mathbb {GIVEN:}}}[/tex]
Diameter of the circle "d" = 7 cm
[tex]\sf \bf {\boxed {\mathbb {TO\:FIND:}}}[/tex]
The circumference of the circle.
[tex]\sf \bf {\boxed {\mathbb {SOLUTION:}}}[/tex]
[tex]\sf\orange{The\:circumference \:of\:the\:circle\:is\: 22\:cm.}[/tex]
[tex]\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:EXPLANATION:}}}[/tex]
We know that,
[tex]\sf\purple{Circumference\:of\:a\:circle \:=\:πd }[/tex]
[tex] = \frac{22}{7} \times 7 \: cm[/tex]
[tex] = 22 \: cm[/tex]
Therefore, the circumference of the circle is 22 cm.
