Assessment of Geometry Part 2

Front

What is the formula for calculating the perimeter of a compound shape?

Back

The perimeter of a compound shape is the sum of the lengths of all its outer sides.

Front

How do you calculate the perimeter of a rectangle?

Back

The perimeter P of a rectangle is calculated using the formula: P = 2(length + width).

Front

What is the formula for the volume of a rectangular prism?

Back

The volume V of a rectangular prism is calculated using the formula: V = length × width × height.

Front

How do you find the surface area of a rectangular prism?

Back

The surface area SA of a rectangular prism is calculated using the formula: SA = 2(length × width + length × height + width × height).

Front

What is the relationship between the height of an object and the length of its shadow?

Back

The height of an object and the length of its shadow are proportional, which can be expressed as a ratio.

Front

If a tree is 12 feet tall and casts a shadow of 9 feet, what is the height of a building that casts a shadow of 24 feet?

Back

Using proportions: (height of tree / length of tree's shadow) = (height of building / length of building's shadow). Thus, height of building = 32 feet.

Front

What is the formula for calculating the area of a triangle?

Back

The area A of a triangle is calculated using the formula: A = 1/2 × base × height.

Front

How do you calculate the circumference of a circle?

Back

The circumference C of a circle is calculated using the formula: C = 2πr, where r is the radius.

Front

What is the formula for the volume of a cylinder?

Back

The volume V of a cylinder is calculated using the formula: V = πr^2h, where r is the radius and h is the height.

Front

What is the difference between surface area and volume?

Back

Surface area measures the total area of the surface of a 3D object, while volume measures the amount of space inside the object.
