Answer:
14m
Step-by-step explanation:
Area = πr²
A = 153.86m²
153.86 = 3.14 *r²
r² = 153.86/3.14
r = √49
r = 7
d = 2r
d = 2*7
d = 14
Answer:
The equation doesn't represent a proportional relationship.
Step-by-step explanation:
- Proportional equations are those linear equations() where the value of b≠0, i.e. the line passes through origin.
- shows a equation that potrays linear relationship between the variables x and y. This type of equation is an example of non-proportional relationship.
- The remaining three equations are in the form of where k is the constant of proportionality. This type of equations represent proportional relationship.
