Answer:
- circumference: 62.8 ft
- area: 314 ft²
Step-by-step explanation:
The circumference is given by the formula ...
C = πd
Using the given numbers, the circumference is ...
C = (3.14)(20 ft) = 62.8 ft
__
The area is given by the formula ...
A = πr² . . . . . where radius r is half the diameter
Using the given numbers, the area is ...
A = 3.14(10 ft)² = 314 ft²
Answer:
9 meters
Step-by-step explanation:
V = 1/3 * pi * r^2 * h
339.12 = 1/3 * pi * 6^2 * h
h = 3 * (339.12)/(36 pi)
h = 9 meters
