Your answer is 150.72.

First, plug in the radius and height into the equation. V=1/3pi*4^2*9
Next solve. 3.14 x 16 x 9 = 452.16
Then you need to divide 452.16 by 3 to get 150.72

What is the height of the building pictured below if its shadow is 100 ft. long?

Evgen [1.6K]

Yeah.. baby, do the SOH CAH TOA with the hula hoop

$\bf 
sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}
$

so.. hmmm we have in the picture, an angle, and two sides,
actually, is the "adjacent" side, and the "opposite"

so.. which of those ratios give us only
the angle
the adjacent side
the opposite side?

ahhha!, is Ms tangent
so $\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(42^o)=\cfrac{h}{100}$

solve for "h"

Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the given equation.

Pani-rosa [81]

y = - 4x +3 when slope is -4

NOTE: Parallel lines have same slope.

For the line passing through point (-5, -6) the slope (m) = -4

Equation of that line:

(y - y1) = m (x -x1)

(y --6) = -4(x --5)

(y + 6) = -4(x + 5)

y + 6 = -4x -20

y = -4x -20 -6

y = -4x - 26
