Question

What is the lateral area of the cone to the nearest whole number? The figure is not drawn to scale. NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!​

Answer 1

25,120 sq. metres

Explanation:

Find the diagram attached

Lateral surface area = πrl

r is the radius

l is the slant height

Given

r = 160/2 = 80m

l = √r²+h²

l = √80²+60²

l = √6400+3600

l = √10,000

l = 100cm

Lateral surface area = 3.14 * 80 * 100

Lateral surface area = 25,120 sq. metres
