Answer:
42pi or 131.95 yards
Step-by-step explanation:
circumfrence of a circle is 2*pi*r
since you added a side wall 1 yard wide you increase the radius of the circle by one yard
so 2*pi*21= 42pi or 131.95 yards
40.75 - 7.05= 33.7
33.7 / 2 = 16.85
16.85 ft. should be on each side of the 7.05 ft. bench
