I think there are three correct answers from the choices. Good ideas that can be used when gathering resources are listing potential formulas, writing down the facts and organizing resources into a table. To gather good resources, organization of every possible source is important.
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
The simplest form of 18/4 is 4.5 or 4 1/2
In this question we have to find the effect of doubling principal, rate or time .
First we have to check the formula which is
As we see that interest is the product of principal, rate and time. So if any of these three doubles, that is if any of these three is twice of the original value, the interest gets doubled.
SO the correct option is C.
X2 is double the amount of x1
