surface are of composite 3d figures quick check answers
1. The surface area of a composite figure can be found by calculating the surface area of each individual shape within the figure and then adding them together.
2. To find the surface area of a cone, use the formula: A = πr^2 + πr√(r^2 + h^2), where r is the radius of the base and h is the height of the cone.
3. To find the surface area of a cylinder, use the formula: A = 2πrh + 2πr^2, where r is the radius of the base and h is the height of the cylinder.
4. An example of a composite figure could be a cylinder with a cone on top. The surface area of this composite figure would be the sum of the surface areas of the cylinder and the cone.
5. To find the total surface area of a composite figure, calculate the surface area of each individual shape and then add them together.
