This is what you do with the string to find the perimeter of the object in the drawing.
What is wrap it around the object and then measure it?
100
This is what circumference measures.
What is the distance around a circle.
100
We use this part of a circle to find the area.
What is the radius?
100
This is the volume of a rectangle with dimensions of 1 in x 2 in x 3 in.
What is 6 cubic inches?
100
This is how you find the surface area.
What is find the area of all of the faces and add them together?
200
Once you know the measure around an object, you have to multiply by this to get the real perimeter
What is the scale?
200
When we multiply the radius by 2, we get this.
What is the diameter?
200
This is why we square the radius to start to find the area of a circle.
What is it makes a little square that's about 1/4 of the circle?
200
This is the volume of a triangular prism, where the base triangle has a base length of 8 and a height of 3, and the height of the prism is 4?
What is 48 cubic inches?
200
This is the surface area of a cube that measures 2 in x 2 in x 2 in.
What is 24?
300
When you measure area, the unit is always this.
What is "squared"?
300
This is a number Greeks discovered to figure the circumference of a circle.
What is pi?
300
This is why we multiply the square of the radius by pi.
What is to cover the circle?
300
This is the volume of an hexagonal prism, in which the hexagon has an area of 24 cm squared, and the height is 3 cm.
What is 72 cm cubed?
300
In order to find the surface area of a triangular prism, you would have to do this.
What is find the area of the triangle, multiply it by two (since there are two), then find the area of the three faces. Then you add all of those together.
400
This is what you count when you start to estimate the area of irregular shapes from a scale drawing.
What is squares?
400
If you divide the circumference by the diameter, you get this.
What is pi?
400
This is the formula for the area of a circle.
What is pi * r squared?
400
This is the volume of a cylinder with a radius of 1 m and a height of 2 m.
What is 6.28 meters cubed?
400
The net for a cylinder has two circles and a rectangle. One dimension of the rectangle is the height of the cylinder. How could we find the other if we knew the radius of the circle on the base?
What is find the circumference of the base?
500
Once you find the number of squares in a drawing of an irregular shape, you do this.
What is multiply by the SQUARE of the scale?
500
This is the formula for the circumference of a circle.
What is 2*pi*r?
500
This is why we cut the circle up into pie shapes to help to figure out the area formula.
What is to make it kind of like a rectangle?
500
In general, this is how you find the volume of a cylinder or prism.
What is find the area of the base and multiply it by the height?
500
This is why we don't have a formula for surface area.
What is because you just add up the areas of all of the faces?
