Area is calculated as:
Substitute 100 for Area
Take π as 3.14. So, the expression become
Divide both sides by 3.14
Solve for r
But diameter = 2 * radius
So:
Area is calculated as:
Substitute 400 for Area
Divide both sides by 3.14
Solve for r
But diameter = 2 * radius
So:
Answer:
m = 3.5
Step-by-step explanation:
So here we will just Cross-Multiply;
2(m) = 9(3)
2m = 27
Divide both sides by 2;
m = 13.5
