Given a circle with measures of (c, d, and r) and a circle with measures of (c', d', and r'), what is c' if
d
d'
= 0.25 and c = 6?
a) 1.5
b) 3
c) 12
d) 24

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

1. minimum

2. 6400

3. eight

hope this !
