Y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.
12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.
1.2 = k
Next write the equation using this k and the h & n.
h = 1.2*n
Now we want to find the height if we have 24 books so plug 24 in for n.
h = 1.2 * 24
h = 28.8 inches

Answer: 22a9
Step-by-step explanation:
Answer:
Divide the diameter by 2 and insert for radius in the equation
Step-by-step explanation:
To find the area of a circle, we can use the equation <em>A=pir^2 </em>or <em>area=pi*radius squared.</em>
The radius is half of the diameter, so just divide the diameter by 2 and plug it into the equation.
Hope this helps!
