Question

If the radius of a coin is 1cm than calculate its area​

Answer 1

3.14 square cm

Explanation:

Since, a coin is circular in shape, hence its area would be equal to the area of a circle.

`\therefore are \: of \: coin = \pi {r}^(2) \\ = 3.14 * {1}^(2) \\ = 3.14 * 1 \\ = 3.14 \: {cm}^(2) \\`
