Volume of a Cylinder Formula: V = πr²h
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
Volume <em>V</em> = 2000π ft³
Height <em>h</em> = 20 ft
Radius <em>r</em> = unknown
<u>Step 2: Solve for </u><em><u>r</u></em>
- Substitute in variables [Volume of a Right Cylinder Formula]: 2000π ft³ = πr²(20 ft)
- [Division Property of Equality] Isolate <em>r</em> term: 100 ft² = r²
- Rewrite: r² = 100 ft²
- [Equality Property] Square root both sides: r = 10 ft
Answer:
around 90 cm because that measure is equal to 180 you divide into 2 so the answer is 90
Answer:
20 people
Step-by-step explanation:
1/8 serves one so 1/4 does 2 . 1/2 does 3 and 1 does 4 so 4 *5 is 20
Answer: $ 23,132.14
Step-by-step explanation:
A=P(1+r/n)^nt
A=9000(1+.068/4)^4x14
Answer:
531.167 ft²
Step-by-step explanation:
Given data
Dimension of pool
Diameter =24ft
Radius =12ft
If the cover must hang by 1ft around, then the diameter is 26ft
Radius =13ft
Area of cover = πr²
Substitute
Area = 3.142*13²
Area =3.143*169
Area =531.167 ft²
Hence the minimum area is 531.167 ft²
