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

Back

The surface area (SA) of a prism can be calculated using the formula: SA = 2B + Ph, where B is the area of the base, P is the perimeter of the base, and h is the height of the prism.

Front

How do you calculate the volume of a pyramid?

Back

The volume (V) of a pyramid is calculated using the formula: V = (1/3)Bh, where B is the area of the base and h is the height of the pyramid.

Front

If the dimensions of a figure are multiplied by a factor, how does that affect the surface area?

Back

If the dimensions are multiplied by a factor k, the new surface area will be k^2 times the original surface area.

Front

What is the formula for the volume of a cone?

Back

The volume (V) of a cone is given by the formula: V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.

Front

What is the relationship between the radius and height of a cone if the volume is known?

Back

To find the height (h) of a cone when the volume (V) and radius (r) are known, rearrange the volume formula: h = (3V)/(πr^2).

Front

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

Back

The surface area (SA) of a cone is calculated using the formula: SA = πr(r + l), where r is the radius and l is the slant height.

Front

What is slant height in a cone?

Back

The slant height (l) of a cone is the distance from the base to the apex along the side of the cone, forming the hypotenuse of a right triangle with the radius and height.

Front

How do you find the surface area of a figure if the dimensions are scaled?

Back

If the dimensions of a figure are scaled by a factor k, the new surface area is k^2 times the original surface area.

Front

What is the significance of rounding in geometry problems?

Back

Rounding is important in geometry to provide a practical answer, especially when dealing with measurements that cannot be expressed as whole numbers.

Front

What is the volume of a cone with a radius of 5 inches and a height of 12.5 inches?

Back

Using the formula V = (1/3)πr^2h, the volume is V = (1/3)π(5^2)(12.5) = 104.72 in³.
