First, you need to multiply 2*21cm, which gives us 42 cm.

Then we multiply it by π, or 22/7 in this case, and 22/7*42cm gives us 132 cm.

So the answer is: 132cm.

Hope this helped! c:

Given that:

(x+2)(2x-5)=54

We have:
$2x^2-x-64=0$

Using the quadratic formula, this is approximately 5.66, so rounded to the nearest whole number, our answer is 6.

To be considered similar triangles, the angles must be the exact same, and the sides must be proportional. The side lengths do not have to be exactly the same, but they must be proportional (like a ratio, suppose one triangle has a side length of 1, and the similar triangle has a side length of 3. The ratio is 1:3, and all sides will follow this ratio.)
