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)

How do you find lateral area of a cylinder?
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).
You cannot use the surface area formula for a right cone to find the surface area of an oblique cone.?
True. This is because the slant height of an oblique cone cannot be defined.

How do you find the surface area of a cone?
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)
Can you Find the lateral area of a cone with height of 7cm and radius of 24 cm?
The lateral area of this cone is 1884.96cm2
Is it true you cannot use the surface area formula for a right cone to find the surface area of an oblique?
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.
How do you find lateral surface area of cube?

How do you find the slant height of a cone if you have surface lateral and radius?
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.
Which of the formulas would find the Lateral Area of a right cone where are is the radius and s is the slant height?
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).
How do you find lateral area of a cylinder?
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).
