Identify the given inside radius and wall thickness.

Here are the solutions to the questions: 1.1.1 Step 1: Identify the given inside radius and wall thickness. The inside radius is r_inside = 21 cm. The wall thickness is 1 cm. Step 2: Calculate the outside radius. The outside radius is the inside radius plus the wall thickness. r_outside = r_inside + wall thickness r_outside = 21 cm + 1 cm r_outside = 22 cm The radius of the outside circle is 22 cm. 1.1.2 Step 1: Identify the inside radius. The inside radius is r_inside = 21 cm. Step 2: Calculate the diameter of the inside circle. The diameter is twice the radius. D_inside = 2 × r_inside D_inside = 2 × 21 cm D_inside = 42 cm The diameter of the inside circle is 42 cm. 1.1.3 Step 1: Identify the given values for radius, height, and . The inside radius is r = 21 cm. The height is h = 35 cm. Use = 3.14. Step 2: Calculate the volume of the inside of the container using the formula V = r^2 h. V = r^2 h V = 3.14 × (21 cm)^2 × 35 cm V = 3.14 × 441 cm^2 × 35 cm V = 3.14 × 15435 cm^3 V = 48465.9 cm^3 The volume of the inside of the container is 48465.9 cm^3. 1.1.4 Step 1: Calculate 55% of the total capacity (volume from 1.1.3). Total capacity V = 48465.9 cm^3. Amount of oil = 55\% of V. Amount of oil in cm^3 = 0.55 × 48465.9 cm^3 Amount of oil in cm^3 = 26656.245 cm^3 Step 2: Convert the amount of oil from cm^3 to litres. Given 1 litre = 1000 cm^3. Amount of oil in litres = 26656.245 cm^31000 cm^3/litre Amount of oil in litres = 26.656245 litres Rounding to two decimal places, the amount of oil in litres is 26.66 litres. 1.1.5 Step 1: Identify the amount of oil in litres and the cost per litre. Amount of oil = 26.656245 litres (from 1.1.4). Cost per litre = R13.00. Step 2: Calculate the total cost. Total cost = Amount of oil in litres × Cost per litre Total cost = 26.656245 litres × R13.00/litre Total cost = R346.531185 Rounding to two decimal places, the total cost is R346.53.
