A cone with a diameter of 18km and a slant height of 20.1km has a total surface area of about 822.78km2
The diameter of the base of a cone is 10.5 cm and its length height its slant height is 10 centimeter the curved surface area is
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
1319.47 meters squared
Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.
It depends on whether the base radius is 8 units or base diameter. It also depends on whether the height is the vertical or the slant height.
The surface area of a cone: SA = pi*r² + pi*r*s (r is radius, s is slant height) The surface area of a pyramid: SA = [1/2 * Perimeter * Slant Height] + [Base Area]
A cone with a diameter of 15 and a slant height of 15 will have a total surface area of about 530.14 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 curved surface area of the cone is 801.11 square units.
Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m
Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
1319.47 meters squared
Knowing the slant height helps because it represents the height of the triangle that makes up each lateral face. So, the slant height helps you to find the surface area of each lateral face.
Total surface area = (piradius2)+(piradius*slant length)
