Find the volume and total surface area of the composite figure below.

Volume = 6467.492mm³

Surface area = 1332.035mm²

Step-by-step explanation:

volume of a cone is r²h. V=10²(24)=7539.822mm³

volume of a sphere is 4/3r³.  V=4/3(8³)=2144.66mm³

Since it's a half of a sphere, it would be 1072mm.33³

7539.822-1072.33=6467.492mm³

Surface area of a cone is r(r+√h²+r²)=1130.97

area of a circle= r²=201.06

surface area of a sphere is 4r²=804.25

Since it's a half sphere, it would be 402.125

1130.97-201.06+402.125=1332.035mm²

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
