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 55.000 meters.

Answer 1

I assume you are in calculus.

Surface area=4PIr^2=4*PI*5500 cm^2
volume= surface area*.1 cm^3

Answer 2

surface of a sphere ... 4 π r^2

approx 9000 m^2

10000 cm^2 in a m^2

Answer 3

use half that area, hemisphere

Answer 4

oops ... missed the hemi
