Surface Area/Composite Figures

Front

What is Surface Area?

Back

Surface Area is the total area that the surface of a three-dimensional object occupies. It is measured in square units.

Front

How do you calculate the Surface Area of a Cylinder?

Back

Surface Area = 2πr(h + r), where r is the radius and h is the height.

Front

What is a Composite Figure?

Back

A Composite Figure is a shape that is made up of two or more simple geometric shapes.

Front

How do you find the Surface Area of a Composite Figure?

Back

To find the Surface Area of a Composite Figure, calculate the Surface Area of each simple shape and then sum them up.

Front

What is the formula for the Surface Area of a Rectangular Prism?

Back

Surface Area = 2(lw + lh + wh), where l is length, w is width, and h is height.

Front

What is the formula for the Surface Area of a Triangular Prism?

Back

Surface Area = bh + (perimeter of base * height), where b is the base area and height is the height of the prism.

Front

What is the formula for the Surface Area of a Sphere?

Back

Surface Area = 4πr², where r is the radius.

Front

What is the formula for the Surface Area of a Pyramid?

Back

Surface Area = Base Area + (1/2 * Perimeter of Base * Slant Height).

Front

How do you find the area of a triangle?

Back

Area = (1/2) * base * height.

Front

What is the area of a circle?

Back

Area = πr², where r is the radius.
