दिया गया है:
त्रिज्या = 5.5 सेमी
संरचना की कुल ऊँचाई = 32.3 सेमी
बेलन की ऊँचाई = 19.1 सेमी
त्रिज्या = 5.5 सेमी
संरचना की कुल ऊँचाई = 32.3 सेमी
बेलन की ऊँचाई = 19.1 सेमी
प्रयुक्त सूत्र:
शंकु का पृष्ठीय क्षेत्रफल = π × त्रिज्या × तिर्यक ऊँचाई
बेलन का पृष्ठीय क्षेत्रफल = 2 × π × त्रिज्या × ऊँचाई
शंकु का पृष्ठीय क्षेत्रफल = π × त्रिज्या × तिर्यक ऊँचाई
बेलन का पृष्ठीय क्षेत्रफल = 2 × π × त्रिज्या × ऊँचाई
गणना:
त्रिज्या = 5.5 सेमी
शंक्वाकार भाग की ऊँचाई = 13.2 सेमी
शंक्वाकार भाग की तिर्यक ऊँचाई = √(त्रिज्या2 + ऊँचाई2)
⇒ √(5.52 + 13.22) = √(30.25 + 174.24)
⇒ √(204.49) = 14.3 सेमी
∴ संरचना का पृष्ठीय क्षेत्रफल = शंक्वाकार भाग का पृष्ठीय क्षेत्रफल + बेलनाकार भाग का पृष्ठीय क्षेत्रफल
⇒ π × त्रिज्या × शंक्वाकार भाग की तिर्यक ऊँचाई + 2 × π × त्रिज्या × बेलनाकार भाग की ऊँचाई
⇒ (22/7 × 5.5 × 14.3) + (2 × 22/7 × 5.5 × 19.1)
⇒ 22/7 × 5.5 × (14.3 + 2 × 19.1)
⇒ 22/7 × 5.5 × 52.5 = 22 × 5.5 × 7.5
⇒ 907.5 सेमी2
∴ संरचना का पृष्ठीय क्षेत्रफल 907.5 सेमी2 है।
त्रिज्या = 5.5 सेमी
शंक्वाकार भाग की ऊँचाई = 13.2 सेमी
शंक्वाकार भाग की तिर्यक ऊँचाई = √(त्रिज्या2 + ऊँचाई2)
⇒ √(5.52 + 13.22) = √(30.25 + 174.24)
⇒ √(204.49) = 14.3 सेमी
∴ संरचना का पृष्ठीय क्षेत्रफल = शंक्वाकार भाग का पृष्ठीय क्षेत्रफल + बेलनाकार भाग का पृष्ठीय क्षेत्रफल
⇒ π × त्रिज्या × शंक्वाकार भाग की तिर्यक ऊँचाई + 2 × π × त्रिज्या × बेलनाकार भाग की ऊँचाई
⇒ (22/7 × 5.5 × 14.3) + (2 × 22/7 × 5.5 × 19.1)
⇒ 22/7 × 5.5 × (14.3 + 2 × 19.1)
⇒ 22/7 × 5.5 × 52.5 = 22 × 5.5 × 7.5
⇒ 907.5 सेमी2
∴ संरचना का पृष्ठीय क्षेत्रफल 907.5 सेमी2 है।

5.5 , 19.1 32.3 ?a)809 2b)885.5 2c)9...
Missing number pattern:
- The numbers given are 5.5, 19.1, and 32.3.
Pattern analysis:
- The difference between 5.5 and 19.1 is 13.6.
- The difference between 19.1 and 32.3 is 13.2.
Applying the pattern:
- To find the next number in the sequence, we need to add 13.2 to the last number, 32.3.
Calculating the missing number:
- 32.3 + 13.2 = 45.5
Final answer:
- Therefore, the missing number in the sequence is 45.5.
- Option 'C) 907.5' is the correct choice.
