Question

The radius of a circle is 7cm. find it's area in terms of pi​

Answer 1

A= π(r)^2 so it would be A= π(7x7) and so A= π(49). Hope it helps :-)

Answer 2

49π

Explanation:

The formula for the area of a circle is
`\pi r^(2)`.

When you insert the numbers, you get
`a=\pi *7^(2)`

`7^(2) =49`

When you put it all together, you get 49
`\pi`

Hope this helped :)
