I’m hoping you mean ratio, 1:9
Step-by-step explanation:
Volume of the barrel = pi * r^2 * h
= 22/7 * (3/2)^2 * 4.5
= 31.82 feet^3
Answer:
2sqrt(10)
Step-by-step explanation:
Use the Pythagorean theorem.
x^2 + 3^2 = 7^2
x^2 + 9 = 49
x^2 = 40
x = sqrt(40)
x = 2sqrt(10)
Volume of sphere = 4/3(pi)(r^3)
Given pi = 3.14, r = 10
4/3(3.14)(10^3)
= 4186.66
Now round to hundredths
Solution: 4186.67 cubic meters
