Question

what is the circumference and diameter of a radius of 3.5 m​

Answer 1

Given,

Radius of circle r = 3.5 cm

To find,

Circumference and diameter of the circle.

Solution,

$\mathcal{\blue{\boxed{Circumference\:of\:circle = 2\pi \: r}}}$

$\sf{ = > 2 \times \frac{22}{7} \times 3.5 = 22cm}$

$\mathcal{\blue{\boxed{Diameter\:of\:circle = 2r}}}$

$\sf{ = > 2 \times 3.5 = 7cm}$

$\sf{\underline{\green{Hence\:the\:answer\:is\:22cm\:and\:7cm}}}$
