For a right circular cone, the lateral area is 565.49 units2
This cone has a lateral surface area of approximately 226.73cm2
The lateral surface area is 18.85 square inches.
Lateral area is 188.5 m2
A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2
First is to understand the terms. Lateral area is the surface area of a 3D figure, excluding the area of any base. Laterial Area (L.A.) of a right cone = pi*radius*slant height radius = 1/2 * diameter L.A. = pi*(1/2)*(4)*(15)=30*pi the formula for this is pi*r*rt(r^2 + h^2). If the diameter is 4, then the radius is 2. If the slant height is 15, then to get the real height we use the Pythagorean Theorem and get rt(221). So the lateral area is pi*2*rt(2^2 + (rt221)^2)...= 2pi*rt(225) = 30pi = 94.248 meters squared which is rounded to 94 meters squared.
The lateral area of this cone is 1884.96cm2
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 approximately 427.26 units2
The lateral area is 122.68m2
This cone has a lateral surface area of approximately 226.73cm2
The lateral surface area is 565.49cm2
Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.
