1. Bellwork  Solve for x!  1.x + 3 = 12  2.x – 8 = - 14  3.5 + x = - 17  4.- 7 + x = - 2

2. SPHERES: VOLUME AND SURFACE AREA Pre-Algebra

3. Spheres  Spheres  A set of all points in space that are a given distance, know as the radius, from a given point, known as the center

4. Volume of a Sphere  VVolume  Pi – 3.14  RRadius v = 4πr 3 3

5. Surface Area of a Sphere  ASurface Area  Pi – 3.14  RRadius
