Q67Multiple choice
Look at the shapes given below and state which of these are polyhedra using Euler’s formula.
- (a)
- (b)
- (c)
- (d)(e) (f) (g) (h) (i) (j) (k) (l) (m) Find the volume of each cylinder. Use 3.14 for π and round to the nearest tenth. 1. 2. 3. 1. Use a similar process to that in earlier Activity to develop the formula for the volume of a cylinder. You will need an empty can or other cylindrical pot. Remove one of the bases. 2. Arrange centimetre cubes in a single layer at the bottom of the cylinder. Fit as many cubes into the layer as possible. How many cubes are in this layer? 3. To find how many layers of cubes would fit in the cylinder, make a stack of cubes along the inside of the cylinder. How many layers would fit in the cylinder? 4. How can you use what you know to find the approximate number of cubes that would fit in the cylinder?
