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

Back

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

Front

What is a y-intercept in a graph?

Back

The y-intercept is the point where the graph intersects the y-axis, representing the value of y when x = 0.

Front

How do you calculate the surface area of a prism?

Back

Surface Area = 2 * Base Area + Lateral Area.

Front

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

Back

Lateral Surface Area = 2πrh, where r is the radius and h is the height.

Front

What is the difference between total surface area and lateral surface area?

Back

Total surface area includes all surfaces of a 3D shape, while lateral surface area only includes the sides, excluding the top and bottom.

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

How do you find the area of a circle?

Back

Area = πr², where r is the radius of the circle.

Front

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

Back

Surface Area = 6a², where a is the length of a side of the cube.

Front

What is the significance of units in surface area calculations?

Back

Units indicate the measurement of area, typically expressed in square units (e.g., cm², m²).

Front

How do you convert square centimeters to square meters?

Back

To convert cm² to m², divide by 10,000 (1 m² = 10,000 cm²).
