Answer:

  90 cm

Step-by-step explanation:

The lateral area of a cylinder is given by the formula ...

  LA = πdh

Filling in the given information, we can solve for h:

  11,880 cm^2 = π(42 cm)h

  h = 1180 cm^2/(42π cm) ≈ 90.0 cm

The height of the cylinder is about 90 cm.

Find the measure of an angle and its complement if one angle measures 24 degrees more than the other.
Vera_Pavlovna [14]

Complementary angles = 90

x+y =90

y=x+24

substitute this in to the equation

x+x+24=90

2x+24=90

subtract 24 from each side

2x = 66

divide by 2

x=33

y = 33+24

y=57

PLSSS HELPPP DUE SOON ILL GIVE BRAINLESS
Kitty [74]

Answer:

D

Step-by-step explanation:

A, B, and C are not linear functions

D would be y=x/2

If you graphed y=x/2, you would get the points (4, 2), (7, 3.5), (8, 4), and (10, 5)

It's more obvious if you notice that y is half of x.
