Lateral surface area of a coner and l are the radius and slant height, respectively.
A very quick "Google" shows
pi x r x l

Quadrupling the base radius will do that.
The answer will depend on what information you have.
find the surface area of the cone and add it to the surface area of the base so the formula would be pi radius s plus pi radius squared
The lateral area... Apex :)
The formula for calculating development surface area of a truncated cone is Avr = π [s (R + r) + R^2 + r^2]. The solution is area (A) subscript r where r is the radius of the top of the truncated cone. In this formula R stands for the radius of the bottom of the cone and s represents the slant height of the cone.
The curved surface area of a cone is: pi*radius*slant length.
This cone has a lateral surface area of approximately 226.73cm2
true
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
surface area is lateral area
The lateral surface area is 549.78mm2
The lateral surface area is 565.49cm2
Wrong, it's True. (Apex)
A cone has two surfaces, lateral surface and its circular surface at the base.The surface area of a cone is the sum of the areas of these two surfaces, i.e. (1) area of the lateral surface and (2) area of its base.Let us consider a right circular cone to find its surface area.The lateral surface area of a right circular cone is π r lwhere,r is the radius of the circle at the bottom of the cone, andl is the lateral height of the coneThe surface area of the bottom circle of a cone is the same as for any circle, π r2Thus the total surface area of a right circular cone is: π r l + πr2 OR π r (l + r)
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A. = πrl, where l is the slant height of the cone.
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
No, the formula is far from simple - requiring elliptical integrals.
