Geometry B 9.2 Day 2

Front

What is the perimeter of a shape?

Back

The perimeter is the total distance around the outside of a shape, calculated by adding the lengths of all its sides.

Front

How do you calculate the perimeter of a rectangle?

Back

To calculate the perimeter of a rectangle, use the formula: P = 2(length + width).

Front

What is the height of a shape?

Back

The height is the vertical distance from the base to the top of the shape.

Front

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

Back

The surface area (SA) is calculated using the formula: SA = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

Front

What is the radius of a circle?

Back

The radius is the distance from the center of the circle to any point on its circumference.

Front

How do you find the area of a circle?

Back

The area (A) of a circle is calculated using the formula: A = πr², where r is the radius.

Front

What is the relationship between diameter and radius?

Back

The diameter is twice the length of the radius: d = 2r.

Front

What is the formula for the volume of a cylinder?

Back

The volume (V) of a cylinder is calculated using the formula: V = πr²h, where r is the radius and h is the height.

Front

What is a right angle?

Back

A right angle is an angle that measures exactly 90 degrees.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around it.
