2.2.1. Determine the time (in words) the sprinkler system was switched off. 2.2.2. Determine the time the sprinkler system was switched on. 2.2.3. Determine the temperature in Fahrenheit if the required constant temperature is kept at \( 25^{\circ} \mathrm{C} \). 2.2.4. Maru bought 100 m pipe for the sprinkling system to cover a bigger area in the green house. Convert the length of the pipe into cm .

Let's solve each part of the problem step by step. ### 2.2.1. Determine the time (in words) the sprinkler system was switched off. To provide an answer, I need the specific time data regarding when the sprinkler system was switched off. Please provide that information. ### 2.2.2. Determine the time the sprinkler system was switched on. Similar to the previous part, I need the specific time data regarding when the sprinkler system was switched on. Please provide that information. ### 2.2.3. Determine the temperature in Fahrenheit if the required constant temperature is kept at \( 25^{\circ} \mathrm{C} \). To convert Celsius to Fahrenheit, we use the formula: \[ F = \frac{9}{5}C + 32 \] Where: - \( F \) is the temperature in Fahrenheit. - \( C \) is the temperature in Celsius. Substituting \( C = 25 \): \[ F = \frac{9}{5} \times 25 + 32 \] Now, let's calculate this. ### 2.2.4. Maru bought 100 m pipe for the sprinkling system to cover a bigger area in the greenhouse. Convert the length of the pipe into cm. To convert meters to centimeters, we use the conversion factor: \[ 1 \text{ m} = 100 \text{ cm} \] Thus, to convert 100 m to cm: \[ 100 \text{ m} \times 100 = 10000 \text{ cm} \] Now, let's perform the calculation for the temperature conversion in Fahrenheit. I'll calculate the temperature in Fahrenheit and confirm the length of the pipe in centimeters. Calculate the value by following steps: - step0: Calculate: \(100\times 100\) - step1: Multiply the numbers: \(10000\) Calculate or simplify the expression \( (9/5)*25 + 32 \). Calculate the value by following steps: - step0: Calculate: \(\frac{9}{5}\times 25+32\) - step1: Multiply the numbers: \(45+32\) - step2: Add the numbers: \(77\) ### Results 1. **Temperature in Fahrenheit**: The required constant temperature of \( 25^{\circ} \mathrm{C} \) is equivalent to \( 77^{\circ} \mathrm{F} \). 2. **Length of the pipe in centimeters**: The length of the 100 m pipe is \( 10000 \text{ cm} \). ### Summary - The temperature in Fahrenheit is \( 77^{\circ} \mathrm{F} \). - The length of the pipe is \( 10000 \text{ cm} \). Please provide the specific times for when the sprinkler system was switched on and off to complete parts 2.2.1 and 2.2.2.
