Pls i need answer with explanation asap.
Mandarinka [93]

Answer:

4 can be rewrite as 2•2, and that's the same as 2².

8 can be rewrite as 2•2•2, and that's the same as 2³

So we can rewrite the whole expression as:

2^x = (2²)⁸•(2³)⁴

2^x = 2¹⁶•2¹²

2^x = 2²⁸

So x = 28

Find the volume for 2 different spheres by randomly choosing different radii.
grigory [225]

Answer:

The volume of a sphere of radius r is:

S = (4/3)*pi*r^3

The volume of a cylinder of radius r and height h is:

C = pi*r^2*h

For this problem the height of the cylinders will be equal to the diameter of the spheres, which is equal to two times the radius.

First, let's use the radius: r = 2.

The volume of the sphere will be:

S = (4/3)*3.14*(2)^3 = 33.49

The volume of the cylinder, where h = 2*2 = 4, is:

C = 3.14*(2^2)*4 = 50.24

Now, let's choose the radius r = 3.

The volume of the sphere will be:

S = (4/3)*3.14*3^3 = 113.04

The volume of a cylinder with this radius and h = 3*2 = 6, is:

C = 3.14*(3^2)*6 = 169.56
