Question

Find the circumference of a circle whose diameter is 35cm​

Answer 1

The circumference is about 110 cm.

Answer 2

Given: The diameter of the circle is $35$cm.

We have to find the circumference of a circle.

As we know that the circumference of the circle is calculated by a formula: $C=2\pi R$

We are solving in the following way:

We have,

The diameter of the circle is $35$cm.

So, the radius of the circle will be:

$\frac{Diameter}{2} \Rightarrow \frac{35}{2} \Rightarrow 17.5$

Now,

The circumference of a circle will be:

$C=2\pi R$

$C=2\times \pi \times17.5\\C=2\times \frac{22}{7} \times 17.5\\\\C=110$

Hence, the circumference of a circle will be$110cm.$
