Answer:
to answer ur question its 64,32,16,8,4
Step-by-step explanation:
Let the length of the radius = r feet.
Diameter = 2r = 2 x 6.8 = 13.6 feet
Circumference = 2
r = 2 x 3.14 x 6.8 = 42.704 feet = approx. 42.7 feet
Answer:
length = 20 cm
width = 9 cm
Step-by-step explanation:
perimeter = 58 cm
58cm = 2*L+2*w equation 1
L = 3w -7 equation 2
where:
L= length
w=width
so we have:
58 = 2(3w -7) +2w
58 = 6w -14 +2w
58 +14 = 8w
72 = 8w
w = 72/8
w = 9 cm = width
we have:
L = 3(9) -7 = 20 cm = length
78 inches if you you know that a foot is 12 inches you can add 12 for every inch then add 6 for the half making it 78 inches.
