Calculate the area of the curved surface area (S.A) of the frustum correct to 2 d.p.

Here are the solutions to your questions:

1a) Calculate the area of the curved surface area (S.A) of the frustum correct to 2 d.p.
The height of the frustum $h = 7.2 \, \text{m}$.
The bottom radius $R = 12 \, \text{m}$.
The top radius $r = 6 \, \text{m}$.

Step 1: Calculate the slant height $L$ of the frustum.
The formula for the slant height is $L = \sqrt{h^2 + (R-r)^2}$.
