Answer:
V = 125.6 in³
Step-by-step explanation:
let V be volume, h the height and r the radius, then the equation relating the quantities is
V = khr² ← k is the constant of variation
To find k use the condition V = 402.12, h = 8, r = 4
402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )
3.14 = k [ note 3.14 is π )
V = 3.14hr² ← equation of variation [ V = πr²h ]
Given r = 2 and h = 10, then
V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6
Answer:
<em>The first value is ten times greater.</em>
Step-by-step explanation:
<u>Numbering System</u>
When we represent numbers in the decimal system, each digit to the left has a value 10 times more than the digit to the right. For example, in the number 44, the 4 to the left side has a value of 40, and it's neighbor to the right side has a value of 4.
In the number 76,600, the 7 has a value of 70,000, while in the number 7,600, its value is 7000. Thus the first value is ten times greater.
Answer:
6
Step-by-step explanation:
-11x-6=5
-11x=5+6
-11x=11
x=11/-11
x=-1
4x+10=4(-1)+10=-4+10=6
