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)
This cone has a lateral surface area of approximately 226.73cm2
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).
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
True. This is because the slant height of an oblique cone cannot be defined.

This cone has a lateral surface area of approximately 226.73cm2
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 formula to find the lateral area ( A ) of a right cone is given by ( A = \pi r s ), where ( r ) is the radius of the base of the cone and ( s ) is the slant height. This formula calculates the surface area of the cone's curved surface, excluding the base.
The lateral area of this cone is 1884.96cm2
No, you cannot directly use the surface area formula for a right cone to find the surface area of an oblique cone. Although both types of cones have a circular base and a slant height, the oblique cone's geometry differs, affecting the calculations for lateral surface area and overall surface area. To find the surface area of an oblique cone, you'll need to account for its specific dimensions and geometry.
Yes, it is true that the surface area formula for a right cone cannot be directly applied to an oblique cone. While both have a circular base and a slant height, the lack of a perpendicular height in an oblique cone affects the calculations for lateral surface area and total surface area. To find the surface area of an oblique cone, you must account for its specific geometry, typically involving more complex calculations.
If a is the side,lateral surface area of cube=4a2
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.
The lateral area ( A ) of a right cone can be calculated using the formula ( A = \pi r s ), where ( r ) is the radius of the base and ( s ) is the slant height. This formula represents the area of the curved surface that connects the base to the apex of the cone.
The surface area of an oblique cone can be calculated using the formula ( A = \pi r (r + l) ), where ( r ) is the radius of the base and ( l ) is the slant height of the cone. The formula consists of the area of the circular base (( \pi r^2 )) and the lateral surface area (( \pi r l )). Since the cone is oblique, it does not affect the surface area calculation, which remains the same as for a right cone. Thus, knowing the radius and the slant height is essential to find the total surface area.
The formula to find the lateral area of a right cone is given by ( LA = \pi r s ), where ( r ) is the radius of the base and ( s ) is the slant height. This formula calculates the curved surface area of the cone, excluding the base. To use it, simply multiply the radius by the slant height and then by (\pi).
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).
