Find the lateral area and surface area of the cylinder Give

Find the lateral area and surface area of the cylinder. Give your answers in terms of pi. a. lateral area: 33 pi m^2: surface area: 75 pi m^2 b. lateral area: 33 pi m^2: surface area: 138 pi m^2 c. lateral area: 84 pi m^2: surface area: = 66 pi m^2: d. lateral area: = 66 pi m^2: surface area: 84 pi m^2 Identify the following as a translation, rotation, reflection, or none of these. a. Reflection b. Translation c. None of these d. Rotation

Solution

19.

This is not transalation as there is no displacement of the figure ABC

It can\'t be a reflection as C and C\' or A and A\' should have been in the same side

If you rotate ABC clockwise keeping B as pivot then C will be at C\' and A will be at A\'.

So, this is a case of D. Rotation
