The circle can be cut into pieces, separated, and fit together to form a parallelogram that has the same area. The height of the parallelogram is the radius and the base is half the circumference, which is r. The area is r(r), which is equal to r2.
Remember, volume is length x width x height. (lxwxh)
5+3 inches is the apparent width. (8)
7+7 inches is the height. (14)
The length is seemingly difficult to solve, but it's easy when you get the hang of it.
You need to divide the toolbox into shapes you can find the volume for and then add it all together.
Let's take 14x5x(7+7). 980.
Now the other half. 16x3x(7+7). 672.
Add.
Volume is 1652 inches.
Answer:
U=76 and R=42 so they are not

Answer:
.83333
Step-by-step explanation:
One fifth of the participants is 1/5*100=100/5=20 is the number of the participants given medicine. So the number of participants given placebo is 100-20=80.
80% of the 80 who took placebo felt improvements, so 20% of 80, which is
(20/100)*80=(2/10)*80=160/10=16 is the number of participants who took placebo and felt no improvement.
P(choosing participant who took placebo and felt no improvement)=
n(participant who took placebo and felt no improvement)/n(participants)
=16/100=0.16
