Question

Find Circumference and area of circle whose diameter 25.
​

Answer 1

Answer:

$diameter = 25 \: unit \\ radius = \frac{25}{2} unit \\ = >12.5 \: unit \\ circumference = 2\pi \: \: r \\ = > 2 \times 3.14 \times 12.5 \\ = > 78.5 \: unit \\ area = \pi \: {r}^{2} \\ = > 3.14 \times {78.5}^{2} = > 19349.465 \: {unit}^{2}$

Here I take π as 3.14.

If you want you can take π =$\frac{22}{7}$

If you take π=$\frac{22}{7}$

Then answer will be different.
