CHAPTER 1 - BASIC TERMS AND CALCULATIONS - 1.2 Surface areas of canal cross-sections and farms · 1.3 Introduction ... Formula:
A = 0.5 x base x height = 0.5 x 3 cm x 2 cm = 3 cm2. Triangle no. 2: base = 3 cm
Cross-sectional area of a fire hose - Math Central - My question is this I know the equations for the final answer but the book skips
how to get to one ... A fire hose has a round cross section, so that's a circular area
. ... That makes the cross-sectional area A = π (2.5 inches)2 = 19.63 inches2.
