Question

Find the surface area of the composite solid. Round your answer to the nearest hundred

Answer 1

you have a cone sitting on a cylinder
surface area of the cone = pi* r^2 + pi* r *l
surface area of a cylinder using only one base = area of base + lateral like a rectangle
total area = + pi *r* l + pi* r^2 + 2 pi* r* h
where r = radius l = slant height of cone and h = height of the cylinder

Answer 2

to the nearest hundred means to 2 decimal places
calculate to 3 places if the 3rd place is 5 or more add 1 to the 2nd decimal digit if the 3rd is less than 5 then drop

Answer 3

ok so i got 204.203522483 for the cone

Answer 4

but idk the other part

Answer 5

also thank you for writting this out for me and helping me get it
