The curved surface area of the cone is 801.11 square units.

Entire surface area of a cone = (pi*radius2)+(pi*radius*slant length) Use Pythagoras' theorem to find the slant length

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.

Slant height is 39.98 cm

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
