Using blue modeling clay with small bits of white clay, cover the balloon to create the earth You then have a 3D shape, perfect for a math class final project How Do You Make a 3D Model of a Sphere?Volume of a Sphere: Volume of a Sphere Question : If one was to hallow out the middle of the sphere, what would be the volume of the space in this sphere if the diameter is 8 inch?Volume of a Sphere: Volume of a Sphere Solution:Circumference of a Sphere: Circumference of a Sphere Question: What is the circumference of the sphere, if the diameter is 8inches?Circumference of a Sphere: Circumference of a Sphere Solution: Formula:Radius of a Sphere: Radius of a Sphere When thinking about our globe we created, we were all curious on how far it was to the center of our sphere. If we wanted to dig to the center of our mini Earth, how far would we have to go if the diameter is 8 inches? (HINT: Figure the radius)Radius of a Sphere: Radius of a Sphere If the diameter of our sphere is 8 inches, we know that the radius is half of that number. Then 'r' = 4 for our given sphere. radius = ½d = ½(8) = 4Surface Area of a Sphere: Surface Area of a Sphere When assembling our shape, the sphere, we realized that we did not have enough clay to cover the whole surface. How could we have figured how much clay we needed for the whole project if our shape was to be 8 inches in diameter? (HINT: Figure the radius)Surface Area of a Sphere: Surface Area of a Sphere If the diameter of our sphere is 8, we know that the radius is half of that number. If then 'r' = 4 for our given sphere, and p = 3.14, then the surface area of the sphere is: surface area = 4 π r 2 = 4 × 3.14 × 4 2 = 200.96Conclusion: ConclusionReferences: References Billstein, R., Libeskind, S., and Lott, J.
