D
Area of a circle is: 兀r✖️r, so 4.1m ➗2 = 2.05, 2.05✖️2.05 = 4.2025
1. Given
2. Addition property
3. Division property
The answer would be 1952 because the display of flag makes a right triangle so we will use Pythagorean theorem in order to find the sides and the sides total is 244 according to theorem, so we multiply by 8 to get the 8 flag display. <span />
Answer:
Height of cylinder is
.
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:
![R = \dfrac{D}{2}](https://tex.z-dn.net/?f=R%20%3D%20%5Cdfrac%7BD%7D%7B2%7D)
So, radius, R =
feet
Let height of cylinder be
feet.
Formula for volume of cylinder is given by:
![V = \pi R^{2} H](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20R%5E%7B2%7D%20H)
Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,
![V = \dfrac{36 \pi}{5} ft^{3}](https://tex.z-dn.net/?f=V%20%3D%20%5Cdfrac%7B36%20%5Cpi%7D%7B5%7D%20ft%5E%7B3%7D)
Using formula for volume, ![V = \pi R^{2} H](https://tex.z-dn.net/?f=V%20%3D%20%5Cpi%20R%5E%7B2%7D%20H)
![\dfrac{36\pi}{5} = \pi \times 3^{2} \times h\\\Rightarrow \dfrac{36\pi}{5} = \pi \times 9 \times h\\\Rightarrow h = \dfrac{4}{5} ft](https://tex.z-dn.net/?f=%5Cdfrac%7B36%5Cpi%7D%7B5%7D%20%3D%20%5Cpi%20%5Ctimes%203%5E%7B2%7D%20%5Ctimes%20h%5C%5C%5CRightarrow%20%5Cdfrac%7B36%5Cpi%7D%7B5%7D%20%3D%20%5Cpi%20%5Ctimes%209%20%5Ctimes%20h%5C%5C%5CRightarrow%20h%20%3D%20%5Cdfrac%7B4%7D%7B5%7D%20ft)
Hence, Height of cylinder is
.
