Answer:

The radius is <u>63.69</u>.

Step-by-step explanation:

Given:

The circumference of a circular track is 400.

Now, to find the radius:

So, to get the radius(r) we put the formula of circumference:

Circumference=2\pi r

⇒ 400=2\times 3.14\times r

⇒ 400=6.28\times r

<em>Dividing both sides by 6.28 we get:</em>

⇒ 63.69=r

⇒ r=63.69

Therefore, the radius is 63.69.

250cm^2

To find the area of shape B we need to find the factor by which you multiply to get from 12 to 15. To find this we divide 15 by 12 to get 1.25. We now multiply the area of shape A (200) by the factor 1.25 to get the answer. The answer is 250cm^2.

Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
