Question

Find the circumference and area of circle whose diameter is 14 cm ( takes pie =22/7

Answer 1

$\textbf{Solution:}$

_______________________________________________

Diameter = 14 cm

Radius(r) = Diameter/2

=> 14/2 = 7cm

Circumference of circle

=> 2 π r

=> 2 × $\frac{22}{7}$× 7

=> 2 × 22

=> 44 cm

Therefore, circumference of circle= 44 cm.
___________________

Area of circle = π r ²

=> $\frac{22}{7}$ × 7 × 7

=> 22 × 7

=> 154 cm²

Therefore, Area of circle = 154 cm²

Hey !!! ^_^

Here is your answer

Formula to find the circumference is

2πr ,

where , r = radius and r = diameter/2 = 14/2 = 7 cm

$2\pi \: r \: \\ \\ = 2 \times \frac{22}{7} \times 7 \\ \\ 22 \times 2 \\ \\ 44cm \:$
The circumference of circle is 44cm

$the \: area \: of \: circle \: \\ = \pi \: {r}^{2} \\ \\ \frac{22}{7} \times {7 }^{2} \\ \\ \frac{22}{7} \times 49 \\ \\ 22 \times 7 \\ \\ 154 \: {cm}^{2}$

I HOPE IT WILL HELP You

Thank you ☺️✌️
