A circular tablecloth has a diameter of 2.0 m. Assuming a fabric roll width of 1.5 m, is the roll wide enough to cut the tablecloth in one piece? What is the minimum length of fabric needed?

The new diameter of the tablecloth (calculated in 1.2.1) is $2.0 \text{ m}$. To cut a circular tablecloth of this size in one piece, the fabric roll width must be at least $2.0 \text{ m}$.

The fabric roll width is not provided in the problem statement. For the purpose of this calculation, we will assume a common fabric roll width of $1.5 \text{ m}$.

Required width = $2.0 \text{ m}$
Assumed roll width = $1.5 \text{ m}$

Since $1.5 \text{ m} < 2.0 \text{ m}$, the assumed fabric roll width of $1.5 \text{ m}$ is not sufficient to cut the tablecloth in one piece.
The answer is $\boxed{\text{No, the fabric roll width is not sufficient (assuming a 1.5 m roll width)}}$.

1.2.4 Calculate the minimum length of fabric required from the roll to cut ONE tablecloth.

To cut a circular tablecloth of diameter $2.0 \text{ m}$ from a roll, the minimum length of fabric required from the roll is equal to the diameter of the tablecloth.

Minimum length = $2.0 \text{ m}$.
The minimum length of fabric required is $\boxed{\text{2.0 m}}$.

1.2.5 Calculate the wastage of fabric per tablecloth if the piece cut is rectangular (length $\times$ width).

To cut a circular tablecloth with a diameter of $2.0 \text{ m}$, the smallest rectangular piece of fabric that can contain it would have a length of $2.0 \text{ m}$ and a width of $2.0 \text{ m}$.

From question 1.2.2, the area of one tablecloth is $A = \pi (1.0 \text{ m})^2 = \pi \text{ m}^2 \approx 3.14159 \text{ m}^2$.

The wastage of fabric per tablecloth is approximately $\boxed{\text{0.86 m}^2}$.

1.2.6 If Madlamini makes 10 tablecloths, calculate the total fabric used in m$^2$.

From question 1.2.2, the area of fabric required for one tablecloth is $\pi \text{ m}^2 \approx 3.14159 \text{ m}^2$.

The total fabric used for 10 tablecloths is approximately $\boxed{\text{31.42 m}^2}$.
