4. The circumference of a circle is 11 pi inches. What is the area, in square inches, of the circle? Express your answer in terms of pi (π). * 5. The diameter of a bike wheel is 27 inches. If the wheel makes 15 complete rotations, how far does the bike travel
The picture is for 5

Area of circle = π ⋅ ( Diameter 2 ) 2 = π ⋅ ( 11 2 ) 2 ≈ 95 sq in

Step-by-step explanation:

Circumference=π⋅DiameterDiameter=Circumferenceπ=11ππ=11inches

given,2πr=11π⇒r=112.

Hope this helps.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
