Calculate the height of a radio, television and telecommunications tower where the scale is 1:11 000; r = 70 mm; d = 7 mm and H = 950 m. Round the answer to first decimal. The height of the tower is:

Step 1: Identify the given values and the objective. The problem asks to calculate the height of a tower. We are given: • Scale: 1:11 000 • r = 70 mm • d = 7 mm • H = 950 m The instruction "Calculate the height" implies that we need to perform a computation using the given scale. If H=950 m were the height of the tower, no calculation would be necessary. Therefore, we assume that one of the measurements in millimeters (r or d) represents the height of the tower on a map or drawing. We will use r=70 mm as the map height for the calculation, as it is a more substantial measurement for a tall telecommunications tower. Step 2: Convert the map height to the real-world height using the scale. The scale 1:11 000 means that 1 unit on the map corresponds to 11 000 units in reality. Map height = 70 mm Real height = Map height × Scale factor Real height = 70 mm × 11 000 Real height = 770 000 mm Step 3: Convert the real height from millimeters to meters. Since 1 meter (1 m) is equal to 1000 millimeters (1000 mm), we divide the real height in millimeters by 1000 to get the height in meters. Real height = 770 000 mm1000 mm/m Real height = 770 m Step 4: Round the answer to the first decimal place. The calculated real height is 770 m. Rounding this to the first decimal place, as per the example given in the question (e.g., 123 becomes 123,0), gives: 770.0 m The height of the tower is: 770.0 m What's next? 📸
