Question

the circumference of the circle is 440 cm find the diameter​

Answer 1

$\bold \green{ans} \orange{wer} = 140cm$

$\bold \purple{radius = \frac{circumference}{2\pi} }$

$\bold \red{radius = \frac{440 \times 7}{2 \times 22} }$

$\bold \green{radius = > \frac{3080}{44} }$

$\bold \orange{radius = 70}$

$\bold \blue{so \: diameter = 70 \times 2 = > 140}$

Answer 2

Answer:

Circumference of circle = 440 cm

Radius= $\sf{ \dfrac{C}{2\pi}=\frac{440\times7}{2\times22}}$

=$\sf{\dfrac{3088}{44}=70\ cm}$

(ii) Diameter = 2 x radius

= 2 x 70 = 140 cm.
