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.
Total surface area: (pi*52)+(pi*5*slant length) = 240.263 square cm to 3 decimal places Note that by using Pythagoras' theorem the slant length works out as the square root of 106
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
A cone with a diameter of 15 and a slant height of 15 will have a total surface area of about 530.14 units2

A pyramid with these measurements are technically impossible to construct. However if you follow the formula the surface area would be a negative amount.
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.
1244.070691 or about 1244 square m
Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m
4x5=20 therfore 20 square metres Each triangular face is 25 sq.m. Therefore the total surface area of the four triangular faces = 100 square metres. If the square base has to be included, add another 25 square metres.
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.
Total surface area= 1/2 times the perimeter of the base times the slant height plus the area of the base Lateral surface area= 1/2 times the perimeter times the slant height
Total surface area: (pi*52)+(pi*5*slant length) = 240.263 square cm to 3 decimal places Note that by using Pythagoras' theorem the slant length works out as the square root of 106
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
Total surface area = (piradius2)+(piradius*slant length)
A cone with a diameter of 15 and a slant height of 15 will have a total surface area of about 530.14 units2
