What is the formula for the surface area of a cylinder?

$$SA = 2\\pi rh + 2\\pi r^2$$ where SA is the surface area, r is the radius, and h is the height.

What is the formula for the lateral surface area of a cone?

$$LA = \\pi r l$$ where LA is the lateral area, r is the radius, and l is the slant height.

What is the slant height of a cone?

The slant height is the distance from the base to the apex along the side of the cone.

How do you find the volume of a cylinder with a radius of 5 cm and a height of 10 cm?

Using the formula $$V = \\pi r^2h$$ , we find $$V = \\pi (5)^2(10) = 250\\pi \\text{ cm}^3$$ .

What is the difference between the volume of a cone and a cylinder with the same base and height?

The volume of a cone is one-third that of a cylinder: $$V_{cone} = \\frac{1}{3}V_{cylinder}$$ .

What is the formula for the area of a rectangle?

$$A = bh$$ where A is the area, b is the base, and h is the height.

What is the formula for the area of a triangle?

$$A = \\frac{1}{2}bh$$ where A is the area, b is the base, and h is the height.
