Answer:
B. 0.73
Step-by-step explanation:
Add all numers so the first is 2/10 = 0.2
then 35/100 = 0.35
and then 16/100 = 0.16
finally 2/100 = 0.02
Now add all decimals which is equal to 73/100 = 0.73 and that's your answer.

Answer:
57.06 unit^2
Step-by-step explanation:
find the area of the rectangle = 12*12 = 144 unit^2
the area of the circle = pi*r^2 = 3.14*8^2 = 201.06 unit^2 (rounded to the nearest hundredth)
then the "shaded area" is the difference
201.06 - 144 = 57.06 unit^2
Answer: 800pi inches
=======================================
Explanation:
The formula to find the circumference of a circle is
C = pi*d
where
C = distance around the circle (aka circumference)
pi = 3.14 approximately
d = diameter
We know that the diameter of the wheel is d = 8, so
C = pi*d
C = pi*8
C = 8pi
is the circumference of the wheel
One full rotation will have the wheel cover a distance of 8pi inches. Imagine that wet paint is on the outer surface of the wheel. If the wheel is rolled out in a straight line, then the wet paint would cover a linear distance of 8pi inches along the flat ground. This is one full rotation, so 100 rotations covers 100*8pi = 800pi inches
Note: if we use pi = 3.14 as the approximation, then the hamster ran approximately 800*pi = 800*3.14 = 2512 inches if the wheel could move
10 divided by 5 =2 floors per second. Divide 2 by 1= 1. 1 floor in 1 second.
