The opposite faces of a cuboid are the same sized rectangles, so find the total area of the three different faces, then double to find the total surface area. The area of the three faces is \(12 ...
pi r^2 h\) Calculate the volume of the cylinder. The measurement shown is the diameter of the circular face, so the radius is 3.5 cm. Substituting the values \(h = 16~cm\) and \(r = 3.5~cm\) into ...
