For the first one: A=pi*r^2*1/8 (1/8 becuase we are finding the area of one pane)
A=pi*16/8
A=2pi
For the second one: First do the larger circle minus the smaller circle (pretend they are whole circles)
A(larger)=pi*18^2
=324pi
A(smaller)=pi*8^2
=64pi
A=324pi-64pi =260pi
Now, a whole circle is 360 degrees so 150 degrees is 5/12 of a circle. We take 5/12 of 260pi to get the answer
260pi*5/12=340.3
Answer:
Step-by-step explanation:
The area of a parallelogram can be calculated with the following formula:
Where "b" is the base and "h" is the height or altitude.
You know that the base of this parallelogram is 8 inches long and the altitude to the base is 10 inches, then:
You need to substutite these values into the formula.
Therefore, the area the parallelogram is:
The jar starts out with 8 marbles in it. Five of them are red.
If you don't peek, the probability of drawing a red marble is
5/8 .
If you have already drawn a red marble on the first try, then
at that point, the jar has only 7 marbles in it, and three of them
are green. Now, for your second draw, if you don't peek, the
probability of drawing a green marble is
3/7 .
The probability of BOTH of those events being successful is
(5/8) x (3/7) = 15/56 = approx 26.79% .
