A=8ft^2
A=l•w
8=l•w
l=8/w
P=2(l+w)
12=2(8/w+w)
12=2(8/w+w/1)
12=2(8/w+w^2/w)
12=16w^2/w
12=16w
w=12/16
w=3/4=0.75ft
l=8/0.75=10.67ft
Answer:
5 is congruent, 6 is not congruent
Step-by-step explanation:
In 5, both shapes have the same side lengths. This means their areas are the same, making them congruent.
In 6, the shapes do not have the same side lengths. This means their areas are not the same, making them not congruent.
Answer:
4 to the -2 power divided by 4 to the 4th power

<h3>(1/4096) is the right answer.</h3>
Answer:
Diameter = 8 cm
Radius = 8/2 = 4 cm
Height = 12 cm
Volume of cone = 1/3πr^2h = 1/3 (4)^2 × 12π
= 64π cubic cm
Radius of lead = 4mm = 0.4 cm
Volume = 4/3πr^3 = 4/3 × (0.4)^3π = 0.256/3π cubic cm
Total number of balls = 64π÷ 0.256/3π = 750
