Question

Diameter of a circle is 2.8cm.
Then find circumference, using the formula ( pi= 22/7).​

Answer 1

$c = 2\pi \: r$

$c = 2 \times \frac{22}{7} \times 1.4$

$c = 44 \times 0.2$

$c = 8.8$

❏ According to the question ፧

${\tt{\color {brown}{✿\: We\: need\: to\: find\: ↷\:}}}$

• ${\tt{\color {purple}{✿\: The\: Circumference\: Of\: The\: Circle.\:}}}$

❏ Given That ፧

${\tt{\color {cyan}{Diameter\: of\: the\: Circle\: ⇾\: 2.8cm\:}}}$

❏ To find the Circumference Of The Circle ፧

${\tt{\color {violet}{Radius\: =\: ?\: (unknown)\:}}}$

❏ To Find Radius ፧

${\tt{\color {purple}{Radius\: →\: Diameter\: ÷\: 2\:}}}$

${\tt{\color {pink}{→(2.8 \div 2)cm}}} \\ {\tt{\color {pink}{→1.4cm}}}$

❏ Now, Finding The Circumference Of The Circle, By Applying The Formula ↷

${\tt{\color {pink}{→2\pi r}}} \\ {\tt{\color {pink}{→(2 \times \frac{22}{7} \times 1.4)}}} \\ {\tt{\color {pink}{→(44 \times 0.2)}}} \\ {\tt{\color {pink}{→}}} \: {\boxed{\tt{\color {pink}{8.8}}}}$

${\boxed{\tt{\color {indigo}{⛤Final\: Answer:-}}}}$

${\tt{\color {cyan}{∴\: Hence,\: The\: Circumference\: Of\: The\: Circle\: is\: 8.8cm.\:}}}$
