The base radius is 3.517 cm
Slant height is 39.98 cm
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.
Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and 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).
The surface area of a cone is the area of the base plus the area of the conical part. This is pi(r2 ) +pi(r)(s)=A If you have A and s, you can solve for r. ( s is the slant height and r is the radius)

The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.

Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and 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).
The area (A) of a cone = πrs where r is the base radius and s is the slant height. 28πs = 3080 : s = 3080/28π = 35.0141 (4dp) Using Pythagoras, Vertical Height (H) = √(s2 - 282) = √(1225.99 - 784) = √441.99 = 21.02 metres.
What do you mean by the radius of 4? Radius is used in circles. Do you mean that the breadth is 4? If so you can use Pythagoras's Theorem to find the 'slant height' (provided that it is a right-angle triangle) (slant height)2=52+42
The surface area of a cone is the area of the base plus the area of the conical part. This is pi(r2 ) +pi(r)(s)=A If you have A and s, you can solve for r. ( s is the slant height and r is the radius)
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.
Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length
Total surface area: (pi*36)+(pi*6*12) = 339.292 square units rounded to 3 decimal places. That is assuming that you meant the slant length and not the slant height because otherwise you would need to use Pythagoras' theorem to find the slant length.
