Suppose the diameter of circle B were 18 inches instead of 8 inches. What is the total cost of the glass for your window now? Will $100 be enough to buy the glass now?

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

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
