With this question, i don't understand it!

Step-by-step explanation:

Data:

d = 8 m

l = 13 m

1. Lateral surface area

The lateral surface area is the side area, excluding that of the base.

The general formula for the lateral surface area L of a cone is

L = πrl

where r represents the radius of the base and l the slant height.

The base is a circle, so

r = d/2 = 8/2 = 4 m

L =π × 4 × 13 =

2. Total surface area

Total surface area = lateral surface area + area of base

S = L + B

The base is a circle, so

B = πr² = π(4)² = π × 16 = 50.36 m²

S = 163.4 + 50.36 =

25/14 or 1.
