Diameter of circle =1.26m
travel distance=circumference of circle ×500 revolution
circumference of circle = one revolution
now,
according to questions (A.T.Q),
finding distance,
circumference of circle = 2πr
=2×22/7x(1.26/2)
=3.96
distance in 500 revolution = 3.96×500 =1980.00

A=10...given

S₁₄=1050
⇒ n/2[2a+(n-1)d]=1050
⇒ 14/2[20+13d]=1050
⇒ 7[20+13d]=1050
⇒ 20+13d=1050/7
⇒ 20+13d=150
⇒ 13d=150-20
⇒ 13d=130
⇒ d=10

20th term = a+19d
                 = 10 + 19×10
                 = 10 + 190
                 = 200

By solving these equation, we get, x = 7 and y = 4. Now, by putting the value of x and y in y = mx-3, we get,
4 = m×7-3
=> m = 7/7
=> m = 1

Gaurav Seth 5 years, 11 months ago

In cylinder,
r=7cm=0.7m
l=15km
=15000m

In tank,
l=50m
b=44m
h=0.21m

Vol.of water in tank=lbh
=50*44*0.21
=462m³

Height of cylindrical pipe=Vol. / πr²
                                      =462/(0.07)²(22/7)
                                      =462/0.0154
                                      =30000m

Time = 30000/15000
= 2 hours
