Q. Two tangents are drawn from a point outside a circle. If the lengths of the tangents are 7 units each, what is the distance from the point to the center of the circle?
A.
7
B.
10
C.
14
D.
√(49 + r²)
Solution
The distance from the point to the center is given by the Pythagorean theorem: distance = √(tangent length² + radius²) = √(7² + r²).
Q. Two trains start from the same point and travel in opposite directions. Train A travels at 80 km/h and Train B at 100 km/h. How far apart will they be after 2 hours?
A.
360 km
B.
320 km
C.
280 km
D.
240 km
Solution
Distance = (Speed of A + Speed of B) × Time = (80 km/h + 100 km/h) × 2 hours = 360 km.
