3 A cylindrical container of diameter 42 cm is filled with 180 litres of milk. (a) Express 180 litres in \( \mathrm{cm}^{3} \). (b) Calculate the cross-sectional area of the container. (c) What is the depth of the milk in the container? A full carton can hold \( 1.15 l \) of milk. (d) How many full cartons can be filled from 180 l ? (e) How much milk, in litres, will be left after filling the cartons?

Clothing: \( 5 \% \) of gross income. A. \( \$ 7,000 \) B. \( \$ 17,500 \) C. \( \$ 5,250 \) D. \( \$ 1,750 \)

2. Bonnie deposited \( \$ 1000 \) in an investment account on the first of January in 2001 . The account pays \( 7.2 \% \) interest compounded annually. How much is the investment worth at the end of 2005 ?

99. La somma e la differenza tra le diagonali di un rombo misurano \( 9,2 \mathrm{~cm} \) e \( 2,8 \mathrm{~cm} \). L'area di un rombo simile a quello dato è \( 86,4 \mathrm{~cm}^{2} \). Calcola il rapporto tra le aree e quello tra i perimetri dei due rombi. \( \left[\frac{1}{9} ; \frac{1}{3}\right] \)
