Question 22 • Geometry
Use the circle area formula, A = πr². For a radius of 7 cm, the area is 3.14 × 7² = 153.86 cm², which is between 135 cm² and 155 cm². The other choices have radii of 6, 8, and 9 cm, which give areas outside that range. So the circle with a 7 cm radius could represent the base of the vase.
