Answer:
15.6
Step-by-step explanation:
First, multiply the midpoint of each class by its frequency, as follows:
Class midpoint frequency midpoint*frequency
0-9 4.5 24 4.5*24 = 108
10-19 14.5 20 14.5*20 = 290
20-29 24.5 32 24.5*32 = 784
Total 76 1182
The mean is computed as the division between the addition of the "midpoint*frequency" column by the addition of "frequency" column.
mean = 1182/76 ≈ 15.6
We know that
[volume of a sphere]=(4/3)*pi*r³-------> r=∛[(3*Volume)/(4*pi)]
r=∛[(3*Volume)/(4*pi)]------> r=∛[(3*3052.08)/(4*pi)]----> r=∛729
r=9 cm
[volume of a cylinder]=pi*r²*h
r=9 cm
h=2*r----> 2*9 -----> 18cm
[volume of a cylinder]=pi*r²*h----->pi*9²*18---> 4578.12 cm³
the answer is
4578 cm³

Answer:
511.8 cubic inches
Step-by-step explanation:
The volume of a sphere is given by ...
V = (4/3)πr³ = (4/3)π(d/2)³ = (π/6)d³ . . . . where d is the diameter
Assuming the dimension of the cube-shaped box is d, the diameter of the ball, the volume of the box will be d³. So, we have ...
85.3π = (π/6)d³
(85.3π)(6/π) = d³ . . . . . the volume of the box
(85.3)(6) = d³ = 511.8 . . . . cubic inches
The volume of the smallest box is 511.8 cubic inches.
