You measure the volume of a stainless steel sphere by placing it into a 100 mL graduated cylinder with an uncertainty of 1 mL, with 20 mL of water initially. After the sphere settles, the graduated cylinder now reads 22 mL. What is the volume with uncertainty? You make a 100 mL, 1 mM solution of glycine in water using a balance with an uncertainty of 0.1 mg and a graduated cylinder with an uncertainty of 1 mL. What is the concentration with uncertainty?
Cylinders
A cylinder is a three-dimensional solid shape with two parallel and congruent circular bases, joined by a curved surface at a fixed distance. A cylinder has an infinite curvilinear surface.
Cones
A cone is a three-dimensional solid shape having a flat base and a pointed edge at the top. The flat base of the cone tapers smoothly to form the pointed edge known as the apex. The flat base of the cone can either be circular or elliptical. A cone is drawn by joining the apex to all points on the base, using segments, lines, or half-lines, provided that the apex and the base both are in different planes.
