Total surface area of the cone: (pi*64)+(pi*8*15) = 184*pi or about 578 square units
A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2
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.
It depends on the dimensions of the base and the height (slant or vertical) of the pyramid.
Total surface area = (piradius2)+(piradius*slant length)
True. This is because the slant height of an oblique cone cannot be defined.
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2
A right cone with a slant height of 6 and a radius of 7 has a total surface area of about 245.04 square units.
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2
The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
Surface Area = Pi*radius(radius + slant height)

678.909
417.83 units squared
Slant height is 7.81 inches.
A cone with a diameter of 18km and a slant height of 20.1km has a total surface area of about 822.78km2
