A solid consists of a cone and a hemisphere. The common diameter of the cone and the hemisphere is 12 cm and the slanting height of the cone is 10 cm. Calculate correct to two decimal places, the surface area of the solid.

---

S.A of solid = prl + 2pr²
= 3.142 x 6 x 10 + 2 x 3.14 x 6²
= 188.52 + 226.224
= 414.744
= 414.74 cm² (2 d.p)
