A solid is in the shape of a cone surmoundted on a hemisphere the radius of each of them is being 3.5cm and the total height of solid is 9.5 cm find the volume of solid |

Answer» TOTAL height = 9.5cm cone height = Total height - hemisphere height cone height = 9.5 - 3.5 = 6 cm r = 3.5cm Volume of solid = 2/3 ×pi ×r^3 + pi×r^2×h = pi×r^2 (2/3×r + h) = 22/7 × (3.5)^2 (2/3 ×3.5 + 6) = 22×0.5×3.5 (2.31 + 6) = 38.5 × 8.31 = 46.81 cm^3 Thanks |
