Find the volume of the cylinder.

Mathematics
1 answer:
zepelin [54]3 years ago
3 0

Answer:

Step-by-step explanation:

The formula for the volume of a cylinder of base radius r and height h is

V = π·r²·h.  Get the radius and height information from the original problem statement and substitute these values into this formula.

For example, if the radius is 3 cm and the height is 4.5 cm, then the volume of this particular cylinder is

V = π·(3 cm)²·(4.5 cm) = 127.2 cm³    (this is an EXAMPLE only)

Answer:

9 1/3, 12 1/2, 14 3/4

Step-by-step explanation:

I assume the formula you’re working with is A=b*h since nothing says otherwise...

((Patio 1))

So you have your area (147) and your base (15 3/4), now you need to plug them in, which should look like this:

147= 15 3/4*h

You need to isolate your h in order to get the missing number, so you should divide both sides by 15 3/4 OR 63/4 ((15*3—>60+3=63))

Dividing by a fraction is the equivalent of multiplying by its reciprocal... so

147 * 4/63 = 588/63 which can be simplified to 84/9 once both the numerator and denominator are divided by 7

In mixed number for it is 9 3/9 which simplified becomes 9 1/3

You solve the other similarly

Find 2 consecutive even numbers such that the sum of the
Elena L [17]

Answer:

14,16

Step-by-step explanation:

Let x be the first even number.

Let y be the 2nd even number.

Given, y - x = 2 (Since they are 2 consecutive even numbers.)

rearranging the equation: y = x+2 (equation 1)

Also given,

y+2x=44\\ (equation 2)

Now we can substitute equation 1 into equation 2 to find x.

x+2+2x = 44\\3x+2 = 44\\3x = 44-2\\3x=42\\x = \frac{42}{3} \\x = 14

Given the smaller even number x, is 14, we will substitute x into equation1 to find y, the bigger even number.

y = 14+2

= 16

Therefore the 2 numbers are 14 and 16.
