Here, Radius(r) = 14 cm. Cost per meter = Rs. 50 Total Cost =? Here, Circumference(C) = 2*pi*r = 2*22/7 * 14 = 88 cm. Now, Total Cost = Cost per meter * Circumference = 50 * 88 = Rs. .....

Here, total length(T) = 440 m. Total rounds = 2. So, One round length = 440/2 =220 m. Since one round is the perimeter of the circle, 2*pi*r = 220, or, 2 * 22/7 * r = 220 or, r = 35 m. Therefore, the radius of the circular ground is 35 .....

The differences between star and moon are given below: -  A star is a luminous body (it gives out light of its own) while    a moon is a non-luminous body (does not give out light of its own). -  A star is a large, .....

You may have learnt about mass and length. Mass and length are the properties of a body that can be measured i.e. expressed in quantity. Such a property that can be measured is called physical .....

x = y/2 So, y = 2x x = z/3 So, z = 3x And x = 2w/3 So, w = .....

We know that, sin180 = 0, sin150 = sin( 180 - 30) = sin30 = 1/2. sin135 = sin( 180 - 45) = sin45 = 1/√2 sin 120 = sin( 180 - 60) = sin60 = √3/2 sin90 = 1. So, using these values, we get, sin2180 + sin2150 + sin2135 + sin2120 .....
