Q1 multiply the 2 "legs" of the triangle
hypotenuse = 44.2 there fore the 2 legs are 27 and 35

|dw:1408225341188:dw|    $\bf \textit{volume of a cylinder}=\pi r^2 h\quad volume=375\quad h=120\quad r=radius=\frac{diameter}{2}
\ \quad \
375=\pi r^2\cdot 120$    solve for "r"  to get the diameter, keep in mind that radius is just half of the diameter
