The lateral area of a cone would be:
One half of circumference of the base multiplied by the slant height.
Basically-
1/2 [( Pi x D) x Slant height)
Where "D" is the diameter of the base of the cone.
(Pi x D) is the Circumference of the base
Slant height - Length of a line from the base to the top of a prism, shape, etc.
(Pi- means 3.14159...(usually abbreviated 3.14) or 22/7)
you can remember first few numbers of pi by seeing how many letters there are in the sentence: May. I have a large container of coffee

How do you find the lateral area of a cone?
LA= 1/2(l*B)where "LA" is lateral area, "l" is lateral height and "B" is the perimeter of the baseMore info:B- otherwise (in a cone) known as 2Ï€r. 2Ï€r is also known as DÏ€ where "D" is diameter
