Answer:
The number of tiles the rug will cover is 54 tiles
Step-by-step explanation:
Here we have,
Total area covered by the rug = 18 ft²
Size of one tile = 1/3 ft²
Therefore the number of tiles that can fit into the the area is given by;
Total area of the rug ÷ Area of one tile
= 18 ft² ÷ 1/3 ft²
Here we note that we are dividing a number by a fraction which is the same as multiplying the number by the inverse of the fraction as follows
= 18 × 3/1 ft²/ft² = 54 tiles
The number of tiles the rug will cover = 54 tiles.
We know that the volume of a Cylinder is
![\pi * r^{2} * H](https://tex.z-dn.net/?f=%20%5Cpi%20%2A%20%20r%5E%7B2%7D%20%2A%20H)
We also know that Pi is 3.14, radius is 3 and Height is 4ft
So we do: 3.14*3*4
and the answer is 37.68
But rounded to the hundredths its 37.69 ft^3

Answer:
<em>y = (x - 4)² - 4 </em>
Step-by-step explanation:
y = x² - 8x + 12
y = ( x² - 2(4)x + 4² ) - 4² + 12
<em>y = (x - 4)² - 4</em>
Answer:
We calculate for the dimensions (the length of the sides) of both the poster and the cube. If the length of the side of the poster is shorter compared to that of the box then, the poster will lie flat in the cube. However, if the poster has a length that is longer than that of the cube then, it will not lie flat in the cube.
length of the poster = sqrt (9 ft^2) = 3 ft
length of the cube = cbrt (30 ft^3) = 3.11 ft
Since, the length of the cube is longer compared to the length of the poster then, the poster will lie flat on the cube
Answer:
I will let you answer this after reading below
Step-by-step explanation:
a=area
![a = \pi {r}^{2}](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cpi%20%7Br%7D%5E%7B2%7D%20)
![r = d \div 2](https://tex.z-dn.net/?f=r%20%3D%20d%20%5Cdiv%202)
write a in terms of d
![a = \frac{\pi {d}^{2}}{ 4}](https://tex.z-dn.net/?f=%20a%20%3D%20%20%5Cfrac%7B%5Cpi%20%20%7Bd%7D%5E%7B2%7D%7D%7B%204%7D)
since it's a semicircle divide a by 2 and that's your answer
