Once a large pink ribbon, the sign of the fight against breast cancer, was erected out of pink post-it notes on a billboard. If the area of the rectangular billboard covered by the ribbon was approximately 3420 square feet, and the width of the billboard was approximately 57 feet, what was the height of this billboard?

60 feet

Step-by-step explanation:

The shape of a billboard = Rectangle

Area of a rectangle = Length(Height) × Width

Area = 3420 square feet

Width = 57 feet

Height = Area of the billboard/Width

Height = 3420 ft²/57 ft

Height = 60 feet

Therefore, the height of the billboard is 60 feet

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
