Since the diameter is 6 cm, the radius is 3 cm. Use the area formula to get 113.04 cm squared. Then, you multiply that by the height of the rod, which is 20 cm. The volume of one rod is 2260.8 cm cubed. To find how much steel is needed for 189 rods, multiple the volume of one rod by 189. Your answer should be 427291.2 cm³.
Answer:
A=80 square feet.
Step-by-step explanation:
First, we find the area of the model. 6*4=24. Now, due to the ratio of 1:40, we know that every inch is actually forty inches. So, you do this:
24*40=960.
So, the area of the actual living room is 960 inches. Or 80 feet.

Answer: The value of 'h' is 3.
Step-by-step explanation: Given that the vertex form of a function is given by
We are to find the value of 'h' when the following function is converted to the vertex form.
From equation (ii), we have
Comparing it with the vertex form (i), we get
Thus, the value of 'h' is 3.
Hello!
Let's solve this equation for y first.
-10x+y=4
Add 10x to both side.
y=10x+4
Now, let's plug in our x-values to find y.
x: -2, -1, 0, 1, 2
y:-16,-6, 4,14,24
I hope this helps!
