Answer:

  • A) The radius is 4 m

Step-by-step explanation:

Volume of cylinder formula:

  • V = πr²h

<h3>Given</h3>

  • V = 64π,
  • h = 4 m

Find r by substituting given values:

  • 64π = πr²*4
  • 64π = 4r²π
  • 16 = r²
  • r = √16
  • r = 4 m

Correct choice is A.

Answer:

radius, r = 4 meters

Volume of cylinder:

  • \sf V = \pi (radius)^2 (height)

Here provided with:

  • radius = ?
  • height = 4 m
  • volume = 64π

Substituting these values in the formula:

\sf  \rightarrow \pi (r)^2 (4) = 64\pi

\sf  \rightarrow 4\pi (r)^2 = 64\pi

\sf  \rightarrow  r^2 = 64\pi /4\pi

\sf  \rightarrow  r^2 =16

\sf  \rightarrow  r=\sqrt{16}  = 4

Answer:

Step-by-step explanation:

This doesn't really make sense.

All you have to do is pick numbers that fall in between the numbers provided.

like:

a = 11

b = 21

C = 21

Sole the system by elimination -4x+9y=9 x-3y=-6
Natalka [10]

Answer:

A) -4x + 9y = 9

B) x -3y = -6

We multiply B) by 3

B) 3x -9y = -18 Then add it to A)

A) -4x + 9y = 9

-x = -9

x = 9

9 -3y = -6

3y = 15

y = 5

A carpenter is putting a skylight in a roof. If the roof measures 10 + 8 by 8 + 6 and the skylight measures + 5 by 3 + 4, what i
Usimov [2.4K]

Answer:

The area is: 77x^2 + 105x + 28, option b.

Step-by-step explanation:

Rectangular area:

The area of a rectangular space is given bt the multiplication of its measures.

Area of the roof:

Dimensions of 10x + 8 and 8x + 6. So

A_{r} = (10x+8)(8x+6) = 80x^2 + 60x + 64x + 48 = 80x^2 + 124x + 48

Area of the skylight:

Dimensions of x + 5 and 3x + 4. So

A_{s} = (x+5)(3x+4) = 3x^2+4x+15x+20 = 3x^2 + 19x + 20

What is the area of the remaining roof after the skylight is built?

Total subtracted by the skylight, which is a subtraction of a polynomial, in which we subtract the like terms. So

A_{r} - A_{s} = 80x^2 + 124x + 48 - (3x^2 + 19x + 20) = 80x^2 - 3x^2 + 124x - 19x + 48 - 20 = 77x^2 + 105x + 28

The area is: 77x^2 + 105x + 28, option b.
