The firebox was 3 feet 4 + 1 ⁄ 2 inches (1,029 millimetres) long and, to obtain the required grate area, the width was extended to 4 ft 4 + 1 ⁄ 2 in (1,334 mm) at the foundation ring. To obtain a liberal firebox depth, the frames were opened out for some length at the rear end, with each frame constructed in two pieces which were connected ...
Earth radius (denoted as R 🜨 or R E) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid (an oblate ellipsoid), the radius ranges from a maximum (equatorial radius, denoted a) of nearly 6,378 km (3,963 mi) to a minimum (polar radius, denoted b) of nearly 6,357 km (3,950 mi).
Measurement of tree circumference, the tape calibrated to show diameter, at breast height. The tape assumes a circular shape. The perimeter of a circle of radius R is .Given the perimeter of a non-circular object P, one can calculate its perimeter-equivalent radius by setting
Regulation 10 × 5-foot carom billiards tables have a playing surface (measured between the noses of the cushions) of 2.84 by 1.42 metres (9.3 by 4.7 ft) with a 5-millimetre allowance. [5] The standard height range of the table, measured from the playing surface to the ground is between 75 and 80 centimetres. [citation needed]
Alternatively, 1 metre (3 ft 3 in) of string is spliced into the original string, and the extended string rearranged so that it is at a uniform height above the equator. The question that is then posed is whether the gap between string and Earth will allow the passage of a car, a cat or a thin knife blade.
Thus for a 2 m (6.6 ft) radius glass tube in lab conditions given above, the water would rise an unnoticeable 0.007 mm (0.00028 in). However, for a 2 cm (0.79 in) radius tube, the water would rise 0.7 mm (0.028 in), and for a 0.2 mm (0.0079 in) radius tube, the water would rise 70 mm (2.8 in).

90-foot (27.43 m) radii on the elevated 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge Chicago 'L'. There is no room for longer radii at this cross junction in the northwest corner of the Loop . The minimum railway curve radius is the shortest allowable design radius for the centerline of railway tracks under a particular set of conditions.
