Question

find the circumference of the circle where radius is 91mm​

Answer 1

$\huge\green{Answer}$

$\large \underline{ \underline{ \sf \: Given : \: \: }}$

Radius of circle = 91 mm

$\large \underline{ \underline{ \sf \: To \: find : \: \: }}$

Circumference of the circle

$\large \underline{ \underline{ \sf \: Solution : \: \: }}$

We know that , circumference of the circle is given by

$\red{ \large \sf\underline{ \: \fbox{Circumference = 2πr} \: }}$

Substitute the values , we obtain

$\begin{gathered} \sf \implies Circumference = 2 \times \frac{22}{ \cancel{7} } \times \cancel{91} \\ \\\sf \implies Circumference = 2 \times 22 \times 13 \\ \\\sf \implies Circumference = 44 \times 13 \\ \\\sf \implies Circumference = 572 \: \: mm\end{gathered}$

Thus , the circumference of the circle is 572 mm

Answer 2

☞Qᴜᴇꜱᴛɪᴏɴ:

Find the circumference of the circle whose radii 91 mm

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☞ɢɪᴠᴇɴ:

Radius of a circle is 91 mm.

☞We know that,

☞ᥴ꠸᥅ᥴꪊꪑᠻꫀ᥅ꫀꪀᥴꫀ = 2πr

━━━━━━━━━

So,

$2 \times 22 \div 7 \times 91 \\ = > 2 \times 22 \times 13 \\ = > 44 \times 13 \\ = > 572mm$
