The total surface area for a silo (base with radius r, cylindrical side with height h, hemispherical cap) is a = 3πr2 + 2πrh. suppose h and r are measured to be h = 20 feet and r = 8 feet to within an error of 1 2 foot for h and 1 4 foot for r. use differentials to estimate the maximum possible error for a (in square feet).

Step-by-step explanation:

The total surface area for a silo A = 3πr^2 + 2πrh.

given

base radius r, cylindrical side with height h, hemispherical cap

h=20 ft  r=8 ft

Δh= 1/2 ft and Δr= 1/4 ft

now, diffrentiating we get

dA= 3π×2r×dr+2π(r×dh+Δr×h)

putting values we get

solving the above equation we get

step-by-step explanation:

should you really be posting this isn't math boi.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
