This cone has a lateral surface area of approximately 226.73cm2
It is possible for some cones A and cylinders B. But in general, the assertion is false.
The lateral surface area is 18.85 square inches.
For a right circular cone, the lateral area is 565.49 units2
Lateral area is 188.5 m2
This cone has a lateral surface area of approximately 226.73cm2
true
surface area is lateral area
The lateral surface area is 565.49cm2
The lateral surface area is 549.78mm2
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)
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.
The lateral surface area is 18.85 square inches.
