Answer: The answer is The radius is 2 inches, and the height is 3 inches. Since the diameter is 4 inches, the radius is half of 4 inches. The volume is 12π=22πh, which means 12π=4πh and h=3.

Answer:

The statement 50π=52πh is equivalent to 50=25h. Since 50 is 25 times 2, h=2 units.

The statement 36π=r2π4 is equivalent to 36=r2⋅4. Since 36 is 4 times 9, r2=9. This implies r=3 units.

The sum of a number, 1/6 of that number, 2 1/2 of that number, and 7 is 12 1/2. Find the number

Whitepunk [10]

Answer:

The sum of a number, 1/6 of that number, 2 1/2 of that number, and 7 is 12 1/2. Find the number?

the number is 2.409

Step-by-step explanation:

based on the question;

let the number N

1/6 of N = (1/6)N

21/2 of N = ( 5/2)N

now, the sum of a number (N) 1/6 of that number(1/6)N , (5/2)N and 7 will be expressed as

N + ( 1/6)N + (5/2)N + 7 = 12 1/2

N + N/6 + 5N/2 + 7 = 25/2

find the lcm of the equation

we have;

(6N + N +15N + 42)/6= 25/2

(22N + 42)/6 = 25/2

Using cross multiplication we have

44N + 84 = 150

Collecting the like terms

44N = 150- 84

44N = 106

Divide both sides by 44

44N/44= 106/44

N = 2.409

Use complete sentences to describe why Set A = { X | X is an even whole number between 0 and 2} = ∅

RoseWind [281]

Consider the Set A = {X | X is an even whole number between 0 and 2 } = $\Phi$ .

Since, whole numbers are the set of numbers starting from zero upto infinity.

Even numbers are the numbers which are exactly divisible by '2'.

So, we have to find the even whole number between 0 and 2.

Since, only '1' is a whole number between 0 and 2 which is not an even number as '1' is not divisible by '2'.

Therefore, there is no even whole number between 0 and 2.

So, this set is empty.

Therefore, A = { X | X is an even whole number between 0 and 2} = $\Phi$
