एक रोलर (roller) का व्यास 84 cm है और लंबाई 120 cm है। एक खेल के मैदान को एक बार समतल करने के लिए 500 चक्कर लगाने पड़ते हैं। खेल के मैदान का में क्षेत्रफल ज्ञात कीजिए।

Answer»

ANSWER:

खेल के मैदान का क्षेत्रफल 1584 मी²।

Step-by-step explanation:

दिया है :

एक रोलर का व्यास = 84 सेमी

एक रोलर की त्रिज्या , = 84/2 = 42 सेमी

एक रोलर की लंबाई , (h) = 120 सेमी

पूरा किया गया एक चक्कर = रोलर का वक्र पृष्ठीय क्षेत्रफल = 2πrh

= (2 × 22/7 × 42 × 120)

= 31680 सेमी²

= 31680 × 1/10000 मी²

[1 सेमी = 1/100 मी]

पूरा किया गया एक चक्कर = 3.168 मी²

खेल के मैदान का क्षेत्रफल = तय किया गए 500 चक्कर

= 500 × 3.168 मी²

= 1584 मी²

अतः, खेल के मैदान का क्षेत्रफल 1584 मी²।

आशा है कि यह उत्तर आपकी मदद करेगा।

P(X)=3x^2-1

Put VALUE of X

If ans. COMES ZERO than it is a zeroes of p(x)

So, (-1/√3) is a zeroes of p(x)

P(x)= 3 (2/√3)^2 -1

33.

X+2y=1.6 , 2x+y=1.4 solve the problem using substitution method

Answer»

Answer:

Step-by-step EXPLANATION: x + 2y = 1.6

=> x = 1.6 - 2y

2X + y = 1.4

=> 2x = 1.4 - y

=> x = 0.7 - y/2

Substituting the value of x from EQ. 1 we get :

1.6 - 2y = 0.7 - y/2

=> 1.6 - 0.7 = -y/2 + 2y

=> 0.9 = 3y/2

=> y = 0.6

=> x = 1.6 - 2(0.6)

=> x = 1.6 - 1.2

=> x = 0.4
