Sec. /]_Operations on Approximate Numbers_371 3115. The sides of a rectangle are 4.02 and 4.96 m (accurate to 1 cm). Compute the area of the rectangle. 3116. Find the quotient of the approximate numbers, which are correct to the indicated decimals: a) 5.684 : 5.032; b) 0.144 : 1.2; c) 216:4. 3117. The legs of a right triangle are 12.10 cm and 25.21 cm (accurate to 0.01 cm). Compute the tangent of the angle opposite the first leg. 3118. Compute the indicated powers of the numbers (the bases are correct to the indicated approximate decimals): a) 0.4158'; b) 65.2'; c) 2 1.5 . 3119. The side of a square is 45.3 cm (accurate to 1 mm). Find the area. 3120. Compute the values of the roots (the radicands are correct to the indicated decimals): a) 1/27715; b) j/65^2 ; c) KsTT. 3121. The radii of the bases and the generatrix of a truncated cone are # = 23.64 cm 0.01 cm; r= 17.31 cm 0.01 cm; / = = 10.21 cm 0.01 cm; ji = 3.14. Use these data to compute the total surface of the truncated cone. Evaluate the absolute and relative errors of the result. 3122. The hypotenuse of a right triangle is 15.4 cm 0.1 cm; one of the legs is 6.8 cm 0.1 cm. To what degree of accuracy can we determine the second leg and the adjacent acute angle? Find their values. 3123. Calculate the specific weight of aluminium if an aluminium cylinder of diameter 2 cm and altitude 11 cm weighs 93.4 gm. The relative error in measuring the lengths is 0.01, while the relative error in weighing is 0.001. 3124. Compute the current if the electromotive force is to 221 volts 1 volt and the resistance is 809 ohms 1 equal ohm. 3125. The period of oscillation of a pendulum of equal length / is to where g is the acceleration of gravity. To what degree of accuracy do we have to measure the length of the pendulum, whose period is close to 2 sec, in order to obtain its oscillation period with a relative error of 0.5%? How accurate must the numbers n and g be taken? 3126. It is required to measure, to within 1%, the lateral surface of a truncated cone whose base radii are 2 m and 1 m, and the generatrix is 5 m (approximately). To what degree of
