Let f be the function that determines the area of a circle (in square cm) that has a radius of r cm. That is, f(r) represents the area of a circle (in square cm) that has a radius of r cm. Use function notation to respond to each item below. To answer these questions, you do not need to know the area of a circle in terms of its radius r. All answers must include f. a. Represent the area (in square cm) of a circle that has a radius of 3.2 cm. Preview b. Represent how much a circle's area (in square cm) increases when the circle's radius increases from 10.1 to 10.11 cm. Preview c. Represent the total area of 6 circles that each have a radius of 12.2 cm. Preview d. A circle has a radius of 22 cm. A second circle has an area that is 55 square cm more than the first circle. Represent the area of the second circle. Preview Box 1: Enter your answer as an expression.
