When the length of string is wound closely around a pen, it goes round six times.

What is the distance once round the pen?

2.2 cm

2.6 cm

$13.2 \mathrm{~cm}$

$15.6 \mathrm{~cm}$

A student wishes to measure accurately the volume of approximately $40 \mathrm{~cm}^{3}$ of water. She has two measuring cylinders, a larger one that can hold $100 \mathrm{~cm}^{3}$ , and a smaller one that can hold $50 \mathrm{~cm}^{3}$ . The water forms a meniscus where it touches the glass.

Figure for Question 3 — CAIE IGCSE Physics

Which cylinder and which water level does the student use to ensure an accurate result?

cylinder

water level

larger one

bottom of meniscus

larger one

top of meniscus

smaller one

bottom of meniscus

smaller one

top of meniscus
