Geometry Exam review

Front

What is the formula for the volume of a cylinder?

Back

The volume V of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.

Front

How do you estimate the height of an object using similar triangles?

Back

To estimate the height, use the ratio of the lengths of the sides of the triangles formed by the object and a reference object.

Front

What is the distance formula in a coordinate plane?

Back

Front

What does it mean to translate a shape in geometry?

Back

Translating a shape means moving it from one position to another without changing its size, shape, or orientation.

Front

What is the formula for the area of a triangle?

Back

The area A of a triangle is given by the formula A = 1/2 * base * height.

Front

What is the definition of a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

How do you calculate the area of a trapezoid?

Back

The area A of a trapezoid is given by the formula A = 1/2 * (b1 + b2) * h, where b1 and b2 are the lengths of the parallel sides and h is the height.

Front

What is the significance of using 3.14 instead of π in calculations?

Back

Using 3.14 is an approximation of π, which can simplify calculations but may lead to less accurate results.

Front

What is the relationship between the radius and diameter of a circle?

Back

The diameter d of a circle is twice the radius r, so d = 2r.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis).
