A circle has a diameter of 3 meters. Which statement about the circumference and area is true?

B is correct.

Step-by-step explanation:

Hello there!

3 x pi is the calculation that you will use for both the area and the circumference, so their values will be equal.

:)

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
