To find the circumference and area of the circle​.

Explanation:

We know that,

Circumference of a circle is,

$2\pi r$

where r is the radius of the circle.

Here, r=3.5

Substitute the value of r, we get

$=2\times\pi\times3.5$

Substitute the value of pi=22/7, we get

$=2\times\frac{22}{7}\times3.5$$undefined$
