A rectangle is such that its area is \(48\text{ cm}^{2}\) and its perimeter is 28 cm. If a rhombus is formed by joining the midpoints of the sides of this rectangle, what is the area of the rhombus?

If a chord of a circle subtends an angle of 60° at the circumference of the circle, then what is the ratio of the radius of the circle and the length of the chord respectively?

A hemispherical tank is full of water. It is connected to a pipe that empties it at a rate of 7 litres per second. How much approximate time (in minutes) will it take to empty half the tank if the internal radius of the tank is 2.1 meters? (Use \(\pi=\frac{22}{7}\) and \(1\text{ m}^{3} = 1000\text{ liters}\))

In a right-angled triangle ABC, the angle at B is 90°. If \(AB = 6\text{ cm}\) and \(BC = 8\text{ cm},\) what is the distance between the centroid G and the orthocenter H?
