1. Find the volume for 5 different spheres by randomly choosing different radii.
Sophie [7]

The volume of the sphere is given by :

V=\frac{4}{3}\pi r^{3}

And volume of cylinder is given as :

V=\pi r^{2}h

So, as given to select the radius randomly and the height of the cylinder will be the diameter of the sphere.

The radius are = 3, 5, 8, 10, 12

And height will be = 6, 10, 16, 20, 24

1. Volume of sphere with radius 3 = \frac{4}{3}*3.14*3*3*3= 113.04 units

Volume of cylinder with radius 3 and height 6 = 3.14*3*3*6=169.56 units

2. volume of sphere with radius 5 = 523.60 units

volume of cylinder with height 10 = 785.40 units

3. volume of sphere with radius 8 = 2144.66 units

volume of cylinder with height 16 = 3216.99 units

4. volume of sphere with radius 10 = 4188.79 units

volume of cylinder with height 20 = 6283.19 units

5. volume of sphere with radius 12 = 7238.23 units

volume of cylinder with height 24 = 10857.34 units

Which of the following is the solution for the inequality below? -3x+2<8
Zepler [3.9K]

Answer:

x>-2

Step-by-step explanation:

First you have to subtract 2 from both sides, which leaves you with -3x=6, then you have to divide -3 on both sides to get the variable by itself. Which is x<-2, but you have to switch the sign because you multiplied/divided by a negative number, then you get left with x>-2........Hope that helped!!!!!!!!!!:)
