Given two circles, A and B. If the area of the smaller circle A is just one-fourth of the area of the larger circle B, what is the ratio of the radius of A to radius of B? |
|
Answer» Answer: Let us say the r1 is the radii of FIRST circle and r2 is the radii of SECOND circle So, r1:r2=3:4 And for area we have a1,a2 be the area of circle1 and circle2 respectively So the RATIO will be a1:a2=π(r1)2:π(r2)2 π will cancel out and ratio will be a1:a2=(3)2:(4)2 a1:a2=9:16 Thanks for reading:) |

A train 125 m long passes a man, running at 5km/hr in the same direction in which the train is going,in 10 seconds. The speed of the train is:A) 45km/hrB)50 km/hrC)54 km/hrD)55 km/hr |
|
Answer» SPEED of the train relative to man : = (125/10) m/sec = (25/2) m/sec. Speed: =[(25/2) X (18/5)] km/hr = 45 km/hr. Let the speed of the train be 'S' km/hr. Then, relative speed : = (S - 5) km/hr. S - 5 = 45 S = 50 km/hr. Therefore The answer Is OPTION B |
