I WONDER - How Do I Measure The Length Of A Sphere?

The video tutorial explains key geometric concepts related to spheres, including the radius, diameter, and how they relate to each other. It also covers how to calculate the volume and surface area of a sphere using the mathematical constant π.

What is the term used for the distance from the center of a sphere to its surface?

• Diameter

• Circumference

• Volume

• Radius

How is the diameter of a sphere related to its radius?

• It is half the radius

• It is equal to the radius

• It is twice the radius

• It is three times the radius

Which of the following is true about the diameter of a sphere?

• It is the shortest distance through the sphere

• It is unrelated to the radius

• It is the longest distance through the sphere

• It is equal to the radius

What mathematical constant is used to calculate the volume and surface area of a sphere?

• π

• e

• i

• φ

Which of the following can be calculated using the constant π for a sphere?

• Only the volume

• Only the surface area

• Both volume and surface area

• Neither volume nor surface area
