pi times l times r (r and l are the radius and slant height, respectively)This can be derived by using a ratio (area/circumference) of the circle with radius L (slant height) with the ratio of the arc (arc-area/arclength). It should look something like this.
(pi*l^2)/(2pi*l) = (arc-area)/(2pi*r)

A right circular cone has radius 5cm and height 8cm Find the lateral surface area of cone?
This cone has a lateral surface area of approximately 226.73cm2
How do you find lateral area of a cylinder?
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
You cannot use the surface area formula for a right cone to find the surface area of an oblique cone.?
True. This is because the slant height of an oblique cone cannot be defined.
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
Which of the follwing formulas would find the surface area of a right cone where s is the slant height and r is the radius LA is the lateral area and BA is the base area?
(pi)r^2+(pi)rs BA+LA
