Joanne has a cylindrical, above ground pool. the depth (height) of the pool is 1/2 of its radius, and the volume is 1570 cubic f
eet. What is the area of its bottom floor? Include equations or inequalities related.
1 answer:
We know that Volume of Cylinder is given by : πr²h
Where : 'r' is the Radius of the Cylinder
'h' is the Height or Depth of the Cylinder
Given : The Height of the Pool is Half of its Radius
⇒ Height of the Pool = 
Given : The Volume of the Pool = 1570 feet³
⇒ πr²h = 1570
⇒ 
⇒ 
⇒ 
⇒ 
⇒ ![r = \sqrt[3]{999} = 10\;(approx)](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B999%7D%20%3D%2010%5C%3B%28approx%29)
As : Area of the Bottom of the Pool is Circular
We know that Area of Circle is given by : πr²
⇒ Area of the Bottom Floor = π × 10² = 314.15 feet²

Answer:
k=10
Step-by-step explanation:
4k + 12= 52
minus 12 on both sides
4k=40
now divide by 4
k=10
You can tell if you make the denominators the same easiest one is 30 for 6 and 5
1/5=6/30
1/6=5/30
now you can see which is bigger
64-25=39
All the square numbers are 1,4,9,16,25,36,49,64,81,100
