- Given - <u>Diameter</u><u> </u><u>of </u><u>circle </u><u>=</u><u> </u><u>1</u><u>0</u><u> </u><u>yards</u>
![radius = \frac{diameter}{2} = \frac{10}{2} \\ \\ \implies \: 5 \: yards](https://tex.z-dn.net/?f=radius%20%3D%20%20%5Cfrac%7Bdiameter%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B10%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%5Cimplies%20%5C%3A%205%20%5C%3A%20yards)
