If log 2 = 0.30103, Find the number of digits in 256 is
Its characteristics is 16.
Hence, the number of digits in is 17.
The length of a rectangular hall is 5m more than its breadth. The area of the hall is 750 m. The length of the hall is
Let breadth = x m
Then, length = (x+5)m
x(x+5) = 750
x² + 5x - 750= 0
x = 25
Find the ratio of the areas of the incircle and circumcircle of a square.
Let the side of the square be x. Then, its diagonal =
Radius of incircle =
Radius of circum circle=
Required ratio =
A rectangular park 60 m long and 40 m wide has two concrete crossroads running in the middle of the park and rest of the park has been used as a lawn. If the area of the lawn is 2109 sq. m, then what is the width of the road?
Area of the park = (60 x 40) = 2400
Area of the lawn = 2109
Area of the crossroads = (2400 - 2109) = 291
Let the width of the road be x metres. Then,
(x - 97)(x - 3) = 0 x = 3.
One side of a rectangular field is 15m and one of its diagonal is 17m. Find the area of field?
Other side = [(17 x 17) - (15 x 15)] = (289 - 225) = 8mArea = 15 x 8 =120 sq. m
