Answer:
here the bucket is of frustum shape so it has 2 radius so r1=40 and r2=20 so to find its volume u will use the formula 1/3into22/7into height into(radius1square+radius2square+radius1 into radius 2)here into means multiplication
to find the area of tin sheet required u must find the curve surface area of frustum it is pie into slant height into (radius 1+radius2)here slant height is √(r1-r2)square+height square here square means multiply the same digit twice
