How do you find the surface area and volume of a sphere?

Aim: How do you find the surface area and volume of a sphere?

SPHERES
- A sphere is the set of all points in the space equidistant from given point called the center.


Formulas:
SA= 4(3.14r^2)
LA= 4(3.14r^2)

For Example:
1. find the Surface area of the Sphere
r=17
formula=4(3.14r^2)

Step 1: write the formula if you want
EX: formula=4(3.14r^2)Step 2: Plug in the given information into the formula
EX: SA=4(3.14r^2) R=17
SA:4(3.14*17^2)
Step 3: Solve the problems
EX: 4(3.14x17^2)
        4(3.14x289)
        4(907.9)
      SA=3631.6
