What is a total area of a pyramid that has a square base with sides 8 and a slant height of 5?

A pyramid with these measurements are technically impossible to construct. However if you follow the formula the surface area would be a negative amount.


What is the surface area of a right cone with a slant height of 6 and a radius of 7?

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.


The total surface area of a cone if its slant height is 21m and dimeter of its base is 24m is?

1244.070691 or about 1244 square m


The total surface area of a cone if its slant height is 21'm and its diameter of its base is 24'm is?

Total surface area of cone = (pi*radius*slant height) + (pi*radius2) Area = (pi*12*21) + (pi*122) = 1244.070691 or about 1244 square m


What is the surface area of a square pyramid with base edge 5 m and slant height 10 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.


What is the surface area of a right cone with slant height of 12 and a radius of 6?

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.


What is the formula for surface area of a pyramid?

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


What is the total surface area of a cone whose radius is 5cm and height is 9cm?

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
