What is the circumference of a 18.5ft circle?

The answer is 56.57.

Step-by-step explanation:

Step by step explanation but hope this helps!

if 18.5 is the diameter, then 58.12 feet

if 18.5 is the radius, then 116.24 feet

Step-by-step explanation:

18.5 x 3.14 = 58.12 feet

58.12 x 2 = 116.24 feet

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
