Is this all the problem wants ?
Answer:
Yes it is is 392.9 m^3
Step-by-step explanation:
Volume of cylinder is π*r^2*h, π times radius squared times height.
Since the diameter is 5.2, the radius is 2.6 (half of it). 2.6^2 = 6.76, and the height is 18.5, 6.76*18.5 = 125.06. Multiply it by pi to get 392.887577258, round it to 392.9, The volume is 392.9 cubic meters.
Given:
mean = 64
standard deviation = 6
sample size = 50
Standard error of the sample mean = standard deviation / √sample size
Standard error = 6 / √50 = 6/7.07 = 0.85
Answer:
Volume of the cylinder = 729π
Step-by-step explanation:
Volume of the sphere = 4/3πR^3 = 972π
The radius of the sphere is evaluated.
R = 9 unit
H = 9
Hence volume of the cylinder = πR^2H = π x 9 x 9 x 9 = 729π
