The volume of a sphere is 3 n cubic centimeters. What is the radius?
Sphere V =
올가
3
32
1. Substitute into the volume formula for V:
2. Multiply both sides of the equation by :
8л = лаз
3. Divide both sides of the equation by n.
8 = 3
4 Take the cube root of both sides:
3 =
3.78 = r
The radius of the sphere is
cm.
If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit
