A bucket of height 8 cm and made up of copper sheet is in the form of frustum of a right circular cone with radii of its lower and upper ends as 3 cm and 9 cmrespectively.Calculate. (i) the height of the cone of which the bucket is a part. (ii) the volume of water which can be filled in the bucket. (iii) the area of copper sheet required to make the bucket

a) How much less is the volume of the cone than b) Using R = the volume of the cylinder of the same height? find the volume of the hemisphere, correct to 2 decimal places. (Use n = - 꼭) 7 cm 7 m - 21 cm Tr2h V1 of a cylinder = Tr’h, V2 of a cone V = Tr2h V,– V½ = rr’h - 3 2nr2h 3 11 =2x Simplify m² = 11 x 7x7 cm c) Using t = 3.14 find the volume of the shape. d) Using n= find the volume of the shaded 7 00 space. -14 cm mm -10 mm - V = V = mm3 cm II -6 cm- II 3.
