Answer:

49π cm²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here diameter = 14, so r = 14 ÷ 2 = 7, then

A = π × 7² = 49π cm²

Answer:

49pi cm^2

Step-by-step explanation:

$a = \pi \: {r}^{2}$

Because the radius is half of the diameter, divide it by 2 to get the radius to place in the formula which is 14 ÷2 = 7

A = pi × 7^2

A= pi × 49cm^2

The cost per unit of the complete units assuming that defective units are sold at Ksh 20 per unit is Rm 93.73.

<h3>What is the cost per unit with defective units?</h3>

The cost per unit with defective units can be computed by subtracting the sales value of the sold defective units from the total production costs, thereby reducing the total production costs, and then dividing the resulting figure by the number of good units.

<h3>Data and Calculations:</h3>

Process 1 Process 2 Total costs

Materials Rm 100,000 150,000 250,000

Labor 50,000 50,000 100,000

Overheads 50,000 20,000 70,000

Total costs 420,000

Input units = 5,000

Output units = 4,480

Defective units = 520 (5,000 - 4,480)

Sales revenue from defective units = Rm 104 (520 x Rm 0.20)

Cost per unit = Rm 93.73 (Rm 420,000 - Rm 104)/4,480

Thus, the cost per unit of the complete units assuming that defective units are sold at Ksh 20 per unit is Rm 93.73.
