Answer:
A
Step-by-step explanation:
A square has 4 right angles
Answer: The total width of iPads is 61.2 inches.
Step-by-step explanation:
Since we have given that
The mean width of 12 iPads = 5.1 inches
So, the Value of 12 iPads is given by

Similarly,
The mean width of 8 kindles =4.8 inches
So, the Value of 8 kindles is given by

We only need total width of the iPads which is 61.2 inches .
Hence, the total width of iPads is 61.2 inches.
Volume of cylinder = pi*r^2*h
Volume of sphere = 4/3*pi*r^3
Let the radius and height be 2
Cylinder = pi * 2^2 * 2 = 8pi = 25.1
Volume = 4/3 * pi * 2^3 = 32/3pi = 33.5
33.5 / 25.1 = 1.33
32/3 pi / 8 pi = 4/3
Four thirds of the cylinder’s volume is the sphere’s volume
