solve both separately

Answer:
I have solved the first one here
Step-by-step explanation:
Circumference of the circle is given by the equation,
2πr where r is the radius.
Substituting the given value of the circumference
2πr= 50.24yd
Therefore, r=50.24/2×π
π=3.14(approx)
r=50.24/6.28
r=8 yd
Similarly, we can answer the the second question but the units are changed.
