We know that
volume of a cylinder=pi*r²*h
where
h=13 cm
r=1 cm
volume of a cylinder=pi*1²*13----> 13*pi cm³

volume of a cone=(1/3)*pi*r²*h
where
r=1 cm
h=3 cm
volume of a cone=(1/3)*pi*1²*3-----> pi cm³

volume of<span> the laser pointer=13*pi+pi-----> 14*pi cm</span>³

from a point 48 feet from the base of a redwood tree, the angle of elevation to the top of the tree is 56.3°. Find the height of
Oksanka [162]

tangent(angle) = Opposite Leg ( Height) / Adjacent Leg ( base)


Tangent(56.3) = Opposite Leg / 48 feet


Opposite Leg = 48 x tangent(56.3) = 71.97


Height = 72 feet ( rounded to the nearest foot).
