Basic math area parameter formula (hindi)

क्षेत्रमिति फॉर्मूले
≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
द्विआयामी आयत/वर्ग/व़त्त :::
►वर्ग
•क्षेत्रफल = भुजा²
•परिमाप = 4 x भुजा
•विकर्ण = भुजा√ 2
.
►आयत
•क्षेत्रफल = लंबाई x चौडाई
•परिमाप = 2(लंबाई + चौडाई)
•विकर्ण = √ (लंबाई² +चौडाई²)
.
►व़त्त
•क्षेत्रफल = πr² (आंतरिक भाग)
•परिधी = 2πr (बाहरी भाग)
.
☞ त्रिआयामी आयत/वर्ग/व़त्त :::
►घन
•आयतन = भुजा³ (आंतरिक भाग)
•वक्रप़ष्ठ = 6भुजा² (बाहरी भाग)
•विकर्ण = भुजा√ 3
.
►घनाभ
•आयतन = लंबाई x चौडाई x उंचाई
(आंतरिक भाग)
•वक्रप़ष्ठ = 2(lb+bh+hl) (बाहरी भाग)
•विकर्ण = √ (लंबाई² + चौडाई² +
उंचाई²)
.
►गोला
•वक्रप़ष्ठ = 3πr² (बाहरी भाग)
•आयतन = (4/3)πr³ (आंतरिक भाग)
.
बेलन
वक्रप़ष्ठ = 2πrh (बाहरी भाग)
संपूर्ण प़ष्ठ = 2πr(h+r)
आयतन = πr²h (आंतरिक भाग)
.
►शंकु
• आयतन =(1/3)πr²h
• क्षेत्रफल = πr(r+s)
.
☞ त्रिभुज :::
►समबाहु :- सभी भुजाएं बराबर
•क्षेत्रफल = (√ 3)/4 x भुजा²
.
►समद्विबाहु :- कोई भी दो भुजा
बराबर
क्षेत्रफल = 1/2 x आधार x उंचाई
.
►विषमबाहु :- सभी भुजाएं असमान
•परिमिती = (a+b+c)/2
•क्षेत्रफल = √ [s(s-a)(s-b)(s-c)]
.
☞ चतुर्भुज :::
►समचतुर्भुज :- सभी भुजाएं बराबर और एक
दुसरे के समांतर
•क्षेत्रफल = 1/2 ( विकर्ण1 x विकर्ण2)
.
►समलंब समचतुर्भुज :- आमने -सामने कि
कोई भी दो भुजा समांतर
•क्षेत्रफल = 1/2 ( समांतर भुजाओं का
योग)x उंचाई
.
►समांतर समचतुर्भुज :- कोई भी दो भुजा
बराबर
•क्षेत्रफल = आधार x उंचाई.

Mathematics Equation problem


(α+в+¢)²= α²+в²+¢²+2(αв+в¢+¢α)
1. (α+в)²= α²+2αв+в²
2. (α+в)²= (α-в)²+4αв b
3. (α-в)²= α²-2αв+в²
4. (α-в)²= f(α+в)²-4αв
5. α² + в²= (α+в)² - 2αв.
6. α² + в²= (α-в)² + 2αв.
7. α²-в² =(α + в)(α - в)
8. 2(α² + в²) = (α+ в)² + (α - в)²
9. 4αв = (α + в)² -(α-в)²
10. αв ={(α+в)/2}²-{(α-в)/2}²
11. (α + в + ¢)² = α² + в² + ¢² + 2(αв + в¢ + ¢α)
12. (α + в)³ = α³ + 3α²в + 3αв² + в³
13. (α + в)³ = α³ + в³ + 3αв(α + в)
14. (α-в)³=α³-3α²в+3αв²-в³
15. α³ + в³ = (α + в) (α² -αв + в²)
16. α³ + в³ = (α+ в)³ -3αв(α+ в)
17. α³ -в³ = (α -в) (α² + αв + в²)
18. α³ -в³ = (α-в)³ + 3αв(α-в)
