Answer:
C. 36π
Step-by-step explanation:
The formula for volume of a sphere is:
V=⁴/₃πr³
We are given diameter: 6
To convert to radius, divide by 2.
6÷2=3. R=3
Plug in to formula
V=⁴/₃π3³
Simplify with multiplication
V=⁴/₃π27
V=36π
The slope =

equation : y + 4 = 1/7 (x+10) ,
y = (1/7)x - 18/7

option with 7 as the answer is correct
