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

Answer:

49π

Step-by-step 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 :)
