Answer:
19.61505096...
Step-by-step explanation:
Area in a circle is pi(ratio)squared
Circumference is pi multiplied by diameter
Ratio is half of diameter
15.7 divided by pi is roughly 5 (4.997465213 to be exact)
Half of 5 is 2.5
pi(2.5)squared is 19.61505096...
Answer:
"13 / 204 ; No, they are dependent events
"
Step-by-step explanation:
The probability of getting a club at first throw is simply total number of clubs divided by total number of cards in the deck.
Total clubs is 13
Total cards in deck is 52
Hence, P(clubs) = 
<em>Since the first card IS NOT replaced, the deck has now 51 cards. We want probability of diamond. There are still 13 diamonds, so probability of diamond now would be 13/51</em>
<em />
Hence, Probability that first card is a club and the second card is a diamond should be 13/52 MULTIPLIED by 13/51
P(1st Club, 2nd Diamond) = 
<u></u>
<u>Note: </u>They are dependent events since we are calculating probability without replacement. The first draw affected the total number of cards in the 2nd draw.
2nd answer choice is right.
Answer:
C. 40.5 cm²
Step-by-step explanation:
Use the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
The bases are the parallel sides, 4.5 cm and 9 cm. The height is the perpendicular distance between them, 6 cm. Filling in these numbers, we have ...
A = (1/2)(4.5 +9)(6) = 40.5 . . . cm²

Determine any equation where n = 6

Add n to both sides

<em></em>
<em> ----- This is 1 equation</em>

Multiply both sides by n

<em></em>
<em> ----- This is another</em>
<em></em>

Add 5n to both sides

<em></em>
<em> ---- This is another</em>
Subtract 10 from both sides


<em></em>
<em> --- This is another</em>
<em>You can have as many equations as possible</em>
I'm guessing you're asking what shape do you get if you cut a hexagon is cut into sixths.
If this hexagon is a regular hexagon, then the shapes would be equilateral triangles.
