Find the volume for 2 different spheres by randomly choosing different radii.

Mathematics
1 answer:
grigory [225]3 years ago
6 0

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

If you get a 50/60 on a test, what percentage is that equal to?
Yuliya22 [10]

Answer:

83%

Step-by-step explanation:

To convert fraction to percents, you have to divide the numerator by the denominator.

So 50 divided by 60 = .833333333333333

Now you have to convert this decimal to a percent by moving the decimal point 2 spaces to the right.

83.333333333%

On tests they usually round percents to the nearest whole percent.

So it would just be 83%

rusak2 [61]
Put the numbers in order
5, 8, 10, 20, 25, 30, 35, 40, 45

Q1 = (8 + 10) / 2 = 18/2 = 9
Q2 -- median = 25
Q3 = (35 + 40)/2 = 75/2 = 37.5

the upper quartile (Q3) = 37.5
