What is the surface area of a cone with 23cm length and a 18 cm diameter?

To calculate the surface area of a cone, you need the slant height (l), radius (r), and the height (h). Given the diameter of 18 cm, the radius is 9 cm (18 cm / 2). The surface area ( A ) is given by the formula ( A = \pi r (r + l) ). Substituting the values, ( l = 23 ) cm and ( r = 9 ) cm, the surface area is approximately ( A \approx 3.14 \times 9 \times (9 + 23) \approx 3.14 \times 9 \times 32 \approx 907.2 , \text{cm}^2 ).
