Use linear approximation to estimate the amount of paint in cubic centimeters needed to apply a coat of paint 0.100000 cm thick to a hemispherical dome with a diameter of 45.000 meters.
[tex]Surface Area of sphere=4\pi(r^2)[/tex]
Since it is hemipshereical, the surface area will be half
[tex]Surface Area of hemispherical dome=2\pi(r^2)[/tex]
The Attempt at a Solution
I converted 45m into 4500cm for the radius. I set dr=.1cm
and the radius to 4500cm.
