Question 22 • Geometry

Liliana is making a vase with a circular base. She wants the area of the base to be between 135 cm squared and 155 cm squared Which circle could represent the base of the vase? Use 3 point 1 4 for pi

Answer
A
Image with description Circle C is shown. Line segment A C is a radius with length 6 centimeters.
B
Image with description Circle C is shown. Line segment A C is a radius with length 8 centimeters.
C
Image with description Circle C is shown. Line segment A C is a radius with length 9 centimeters.
D
Image with description Circle C is shown. Line segment A C is a radius with length 7 centimeters.

Explanation

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.
