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. represent the area (in square cm) of a circle that has a radius of 3.7 cm.

a box 3 3/4 feet long or 4+ feet.

step-by-step explanation:

c

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

i think its a and d
