If its a triangular based pyramid (tetrahedron) then it will have 4 equilateral triangle faces and so find the area of one face and multiply it by 4 to give the total surface area.

It depends on whether or not the tetrahedron is regular. There is nothing in the question to indicate that it might be regular. In that case the easiest way to calculate the surface area is to sum the areas of each of its 4 faces.

Total surface area = (2*pi*radius2)+(diameter*pi*height)

Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units

Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units

Find the area of each face separately and then add them together for the total surface area.

Find the surface area of each face then add them together to give the total surface area.

Total surface area = (2*pi*radius2)+(diameter*pi*height)

The surface area of a space figure is the total area of all the faces of the figure

If you want to find the surface of something, you must first specify which shape or object you wish to find the surface of, and need to say which area you are looking for, Lateral or Total surface area. Then someone will be able to answer your question.

1. Find the surface area of the whole cylinder 2. Find the area of one of the two circles on either end of the cylinder 3. Multiply the circle's area by two and subtract their area from the total surface area 4. Now you have the surface area of an unclosed cylinder!

Total surface area = (2*pi*r2)+(pi*r2) Area = 300*pi in square units

Total surface area = (2*pi*r2)+(2*pi*r*height) Surface area = 69.11503838 or 69 square units

To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
