A grain silo consists of a cylindrical main section and a hemispherical roof. The cylindrical part is 30 ft tall. Express the total volume of the silo (including the part inside the roof section) as a function of the radius of the silo.V(r)=
Not enough information,need to know the diameter
1. cylinder volume = pi r^2 h 2. sphere volume = V = (4 Pi/3)r3 = (Pi/6)d3/2
i'm maths instructor sending you this concepts: a million) do no longer restoration unique time, 2) pastime is the motivating component to benefit arithmetic. 3) very maximum extreme element to be reported is practice Examples and workouts in simple terms. 4) do no longer bypass over any financial ruin. 5) once you're a student of state board,do no longer learn something from out area the text cloth e book. 6) Refer previous twelve months questions. 6) if ISC, you will desire to refer extra books. 7) pastime and hard artwork with valuable would carry you 100p.c.successes
V top=(2pi/3)R^3 V cyl=30piR^2 Vr=piR^2[30+(2R/3)] God bless you.
