If the area of a circle with radius 'r' is equal to CSA of a cone of radius 'R' and slant height 'L', then R = .
Given, Area of circle = Curved surface area of cone
⇒πr2=πRL
⇒R=r2L
If a circle and a sphere have the same radius, then CSA of sphere is times the area of the circle.
If the area of a circle with radius r is equal to the curved surface area of a cone with radius r1 and slant height l then the value of r1 in terms of r and l is:
the lateral surface area of a cylinder is equal to the curved surface area of a cone if the radius be same.find the radius of the height of cylinder and slant height of cone?
If the area of a circle with radius r is equal to the curved surface area of cone with radius r1 and slant height l then the value of r1 in terms of r and l is:
