In summary, a point is a location in space with no size, while a line is a straight path with no thickness. To calculate the area of a triangle, use the formula A = 1/2 * base * height. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. To find the volume of a cylinder, use the formula V = π * r^2 * h. Perimeter is the distance around a 2D shape, while circumference is the distance around a circle.

Geometry Help??

Hi

I need help with some geometry. I did question 3.1. (Draw the graph) but if you can please do it again so I can make sure it's right otherwise just do 3.2 - 4.4

Check out the link for the questions: http://postimage.org/image/2gqquln7o/


I need the whole of question 3 and 4 done please.


Thanks a lot!

No. We don't work like that. Show us what your answer was and we can tell you whether it is correct or not.
 

1. What is the difference between a point and a line?

A point is a location in space that has no size or dimension. It is often represented by a dot and has no length, width, or depth. A line, on the other hand, is a straight path that extends infinitely in both directions. It has no thickness but has length and direction.

2. How do you calculate the area of a triangle?

The formula for calculating the area of a triangle is A = 1/2 * base * height, where A is the area, base is the length of the base of the triangle, and height is the height of the triangle measured perpendicular to the base. Simply plug in the values for base and height into the formula and solve for A.

3. What is the Pythagorean Theorem?

The Pythagorean Theorem is a mathematical principle that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. It can be written as a^2 + b^2 = c^2, where a and b are the lengths of the legs of the triangle and c is the length of the hypotenuse.

4. How do you determine the volume of a cylinder?

The formula for calculating the volume of a cylinder is V = π * r^2 * h, where V is the volume, r is the radius of the base, and h is the height of the cylinder. Simply plug in the values for r and h into the formula and solve for V. Note that π is approximately equal to 3.14.

5. What is the difference between perimeter and circumference?

Perimeter is the distance around the outside of a two-dimensional shape, such as a square or a rectangle, and is calculated by adding up all of the side lengths. Circumference, on the other hand, is the distance around the outside of a circle and is calculated using the formula C = 2πr, where C is the circumference and r is the radius of the circle. In other words, perimeter is for polygons and circumference is for circles.
