AQA GCSE · Question 03.2 · Geometry and Measures
On this centimetre grid, draw the front elevation of the building. Use a scale of 1 cm to 10 m.
On this centimetre grid, draw the front elevation of the building. Use a scale of 1 cm to 10 m.
How to approach this question
1. Understand what a "front elevation" is (a view from the front).
2. For a cylinder, the front elevation is a rectangle.
3. The width of the rectangle will be the diameter of the cylinder, and the height will be the height of the cylinder.
4. Use the given scale (1 cm to 10 m) to convert the real dimensions (40 m diameter, 55 m height) into the dimensions for your drawing.
5. Use a ruler to draw the rectangle on the grid with the correct dimensions.
Full Answer
The front elevation is a view from the front. For a cylinder, this is a rectangle.
The width of the rectangle is the diameter of the cylinder (40 m).
The height of the rectangle is the height of the cylinder (55 m).
Using the scale 1 cm : 10 m:
Width on drawing = 40 / 10 = 4 cm.
Height on drawing = 55 / 10 = 5.5 cm.
The answer is a rectangle of 4 cm by 5.5 cm drawn on the grid.
A front elevation is a 2D drawing of an object as seen from the front. For a cylinder, this view is a rectangle.
The width of this rectangle is the diameter of the cylinder, which is 40 m.
The height of the rectangle is the height of the cylinder, which is 55 m.
The scale is 1 cm to 10 m.
We convert the real dimensions to the drawing dimensions:
Width on drawing = 40 m / 10 = 4 cm.
Height on drawing = 55 m / 10 = 5.5 cm.
You should draw a rectangle that is 4 cm wide and 5.5 cm high on the grid.
Common mistakes
✗ Drawing the plan (a circle) instead of the front elevation.
✗ Mixing up width and height.
✗ Incorrectly applying the scale, for example drawing a 40 cm by 55 cm rectangle.
