How do you find the volume of a sphere

The video tutorial covers the concept of calculating the volume of a sphere, starting with an introduction to the idea of a sphere as a 3D circle. The teacher explains the formula for volume, which is 4/3 times π times the radius cubed. An example problem is solved, demonstrating the calculation steps, including identifying the radius and using the formula. The tutorial concludes with a summary of the key points, emphasizing the difference between volume and area units.

What is the formula for calculating the volume of a sphere?

• π times the radius squared

• 4/3 times π times the radius cubed

• 2 times π times the radius cubed

If the radius of a sphere is 10, what is the first step in calculating its volume?

• Multiply 10 by π

• Cube the radius

• Square the radius

• Multiply the radius by 4/3

What is the value of 10 raised to the third power?

• 100

• 100,000

• 10,000

• 1000

How do you adjust the decimal point when multiplying by multiples of 10?

• Subtract a zero from the end

• Add a zero to the end

• Move the decimal point to the right

• Move the decimal point to the left
