Find CSA of cylinder whose circumference is 11cm and its height is twice itz diameter​
e-lub [12.9K]

Answer:

  77.03 cm²

Step-by-step explanation:

The appropriate formulas are ...

  CSA = Ch . . . . . curved surface area, C=circumference, h=height

where

  C = πd

or

  d = C/π

__

Here, we have ...

  h = 2d = 2C/π

  C = 11 cm

so the curved surface area is ...

  CSA = (11 cm)(2(11 cm)/π) = 242/π cm² ≈ 77.03 cm²

Fraction 3 over 4x = Fraction 1 over 5. x = ___?
umka21 [38]

Answer:

\large\boxed{x=3\dfrac{3}{4}}

Step-by-step explanation:

\dfrac{3}{4x}=\dfrac{1}{5}\qquad\text{cross multiply}\\\\(4x)(1)=(3)(5)\\\\4x=15\qquad\text{divide both sides by 4}\\\\x=\dfrac{15}{4}\\\\x=3\dfrac{3}{4}

Rewrite the following linear equation to slope form :y+2=7(2x-4)
garik1379 [7]

Answer:

y = 14x -30

Step-by-step explanation:

The slope intercept form is:

y = mx + b,

Slope intercept form is useful for finding the slope and y intercept of a line, hence why it is called "slope intercept" because it is easy to see the slope and the y intercept of a line in this form. Since the slope denoted by m, and y intercept denoted by b are clearly given.

y + 2 = 7(2x - 4)

Distribute 7 across the parentheses by multiplying x and 2x and 4 by 7.

y+2 = 14x - 28

subtract 2 from both sides. This cancels the 2 on the left and moves it to the right, while keeping the equation balanced.

y+2 -2 = 14x - 28 -2

y  = 14x - 30

y = 14x -30

As you can see our y = 14x -30 now looks like the point slope equation we had above. m = 14, and  b = -30. This means the line goes up 14 for every single unit you move to the right, and intersects the y axis at  (0, -30).
