## 6 Questions

What is the formula for finding the volume of a cylinder?

$ ext{Volume} = ext{Base Area} imes ext{Height}$

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

$ ext{Surface Area} = ext{Base Area} + ext{Lateral Area}$

State the Pythagorean theorem.

$a^2 + b^2 = c^2$

Explain the steps involved in finding the area of a trapezium.

The area of a trapezium can be found by adding the lengths of the parallel sides, multiplying by the height, and dividing by 2.

Describe the process of finding the perimeter of a rhombus.

To find the perimeter of a rhombus, add all four sides together.

Explain the concept of finding the mean of a set of numbers.

The mean of a set of numbers is calculated by adding all the numbers together and then dividing by the total count of numbers in the set.

## Study Notes

### Formulas and Theorems

- The formula for finding the volume of a cylinder is V = πr²h, where V is the volume, π is a constant approximately equal to 3.14, r is the radius of the base, and h is the height of the cylinder.

### Surface Area of a Cone

- The formula for the surface area of a cone is SA = πr(r + l), where SA is the surface area, π is a constant approximately equal to 3.14, r is the radius of the base, and l is the slant height of the cone.

### Pythagorean Theorem

- The Pythagorean theorem states that a² + b² = c², where a and b are the lengths of the legs of a right-angled triangle, and c is the length of the hypotenuse.

### Area of a Trapezium

- To find the area of a trapezium, follow these steps:
- Measure or calculate the lengths of the parallel sides (a and b) and the height (h) of the trapezium.
- Multiply the height by the average of the lengths of the parallel sides: Area = (a + b) / 2 × h.

### Perimeter of a Rhombus

- To find the perimeter of a rhombus, follow these steps:
- Measure or calculate the length of one side of the rhombus.
- Multiply the length by 4, since all sides of a rhombus are equal: Perimeter = 4 × side length.

### Mean of a Set of Numbers

- To find the mean of a set of numbers, follow these steps:
- Add up all the numbers in the set to find the total sum.
- Divide the total sum by the number of items in the set: Mean = Sum / Number of items.

Test your knowledge of mathematical formulas with questions on the volume of a cylinder, the Pythagorean theorem, and the surface area of a cone.
