Question 12 • Mathematics II

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 A circle has a radius labeled 6 centimeters.
B
Image with description A circle has a radius labeled 7 centimeters.
C
Image with description A circle has a radius labeled 8 centimeters.
D
Image with description A circle has a radius labeled 9 centimeters.

Explanation

Use the circle area formula, A = πr². For a radius of 7 cm, A = 3.14 × 7² = 153.86 cm², which is between 135 cm² and 155 cm². The other listed radii produce areas outside that range, so a circle with a 7-centimeter radius could represent the base.
