We know that the area of a semicircle = 1/2(πr^2)
r = the radius
We also know that the area of a rectangle = xy
x = width
y = length
In our problem,
r = w
x = w
y = w + 5
A(w) = w(w + 5) - 1/2(πw^2)
Let's simplify the right side of the function.
A(w) = w^2 + 5w - 1/2πw^2
17 wax cubes with volume of 27 cm³ each would be needed to make the candle with a volume of 452.16 cm³
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Volume of cylinder = π * radius² * height
Volume = π * 4² * 9 cm = 452.16 cm³
Volume of the cube = 3 cm * 3 cm * 3 cm = 27 cm³
Number of cubes needed = 452.16 cm³ / 27 cm³ = 16.75

There ar eno decimal places in 3.2x0 because 0x anything is 0 and 3 decimal places in 0.77x1.6. You can juat count the amout of places and that is the answer unless 0 is in the problem.
Answer:
The answer to your question is the third histogram
Step-by-step explanation:
What we must check in a histogram is that the x-axis is represented the intervals and in the y-axis is represented the frequency.
The first histogram is incorrect just by observing the first bar, we notice that the correct frequency from 0 to 4 is 3, not 14. This histogram is incorrect.
Also, the second histogram is incorrect, the frequency of the first category is 3, not 12. This histogram is wrong.
The third histogram is correct because all the bars are in agreement with their frequencies.
The last histogram is incorrect, for example, the last frequency is 12, not 3.
