To quadruple the lateral surface area of a cone, you need to increase either the radius or the height of the cone. The lateral surface area ( A ) of a cone is given by the formula ( A = \pi r l ), where ( r ) is the radius and ( l ) is the slant height. To achieve quadrupling, you could multiply the radius ( r ) by 2 or the slant height ( l ) by 2, or a combination of both, as long as the product results in four times the original area.
true
surface area is lateral area
The lateral surface area is 549.78mm2
The lateral surface area is 565.49cm2
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)
Quadrupling the base radius will do that.
This cone has a lateral surface area of approximately 226.73cm2

Wrong, it's True. (Apex)

The curved surface area of a cone is: pi*radius*slant length.
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
The lateral area is 188.5 square inches. The surface area is 301.59 square inches.
It is possible for some cones A and cylinders B. But in general, the assertion is false.
