Answer:
283 cm²
Explanation:
To find the surface area of the cone, we don't need the height since we already have the slant height.
The surface area of a cone is given as:
A = (π * r²) + (π * r * L)
Where r = radius of base of cone
L = slant height of cone
From the question, r = 5 cm and L = 13 cm
Hence:
A = (π * 5²) + (π * 5 * 13)
A = 78.55 + 204.23
A = 282.78 cm² = 283 cm² (approximating to the nearest whole number)
The approximate surface area of the cone is 283 cm²
