Side 22 - A circle is a plane figure contained by one line, which is called the circumference, and is such, that all straight lines drawn from a certain point within the figure to the circumference are equal to one another : 16. And this point is called the centre of the circle.
Side 41 - To the sum of the areas of the two ends of the frustum, add the square root of the product of the diameters of the two ends, this result multiplied by one-third of the perpendicular height of the frustum will give the cubic contents.
Side 43 - From half the sum of the three sides subtract each side severally. Multiply the half sum and the three remainders...
Side 26 - A cone is a solid figure described by the revolution of a right-angled triangle about one of the sides containing the right angle, which side remains fixed.
Side 21 - A plane angle is the inclination of two lines to one another in a plane, which meet together, but are not in the same direction.
Side 117 - Let the given velocity of a wheel containing 54 teeth equal 16 revolutions per minute, and the given diameter of an intermediate pulley equal 25 inches, to obtain a velocity of 81 revolutions in a machine ; required the number of teeth in the intermediate wheel, and diameter of the last pulley. v/81...
