Surface Area = Pi*radius(radius + slant height)
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 slant height of 6 and a radius of 7 has a total surface area of about 245.04 square units.
A cone with a radius of 7 and a slant of 12 has a total surface area of about 417.83 units2
The lateral area is, I think, 35pi and the surface area is 60pi.188.40 units sq.
Surface Area = Pi*radius(radius + slant height)
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
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
Entire surface area of a cone: pi*radius^2 plus pi*radius*slant length
A cone with a radius of 7 and a slant of 12 has a total surface area of about 417.83 units2
75.4 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.
