Answer:
Step-by-step explanation:
the circumference for the circle is 23 yd.
it's 2
2376
Here we have two right triangles. And in such case we have to use altitude rule which is
ratio of part of hypotenue and altitude= ratio of altitude and remaining part of hypotenuse
So we get
r/h =h/s
So the correct option is s .
BC^2=10^2+30^2
Using pythagorean theorem
