Answer:
the volume is 157.08
Step-by-step explanation:
formula is v=1/3hπr²
1: V=1/3(6)π(5)²
2. V=1/3(6)π(25)
3:V=2*π*25
4: V=157.079

Answer:
Circle requires ≈ 20 m of edging
Step-by-step explanation:
A = πR²
R = √(A/π)
C = 2πR = 2π√(A/π)
C = 2π√(30/π) = 19.41625... ≈ 20 m 
square needs ≈ 22 m of edging 
equilateral triangle needs ≈ 25 m of edging
