Answer:
10π (after use calculator)
Step-by-step explanation:
A = 2πr
so,
A = 2(π)(5)
A = 10π
then use your calculator
and u will get the answer
<span>Cylinder Volume = </span><span>π <span>• r² • height (or length)
</span></span>
<span>Cylinder Volume = PI * 7^2 * 15
</span>
<span><span>Cylinder Volume = PI * 49 * 15</span>
</span>
Cylinder Volume =
<span>
<span>
<span>
2309.07 OR it equals
PI * 735
answer is "b"
(actually the answer should read 735 * PI cm^3. It is in cubic centimeters and it is NOT PI that is being cubed.)

Step-by-step explanation:
Out of the 7 coins, one is fake and has heads on both sides. So, fake coin on toss coin will always turns up to be head.
Therefore, to obtain the probability of exactly 5 heads is:
probability of getting exactly 4 heads from the 6 fair coins
Probability of getting heads, p =
Probability of not getting head, q = 1 - p =
Now, by Binomial distribution with:
p = = 0.5
q = = 0.5
n = 6
P(X = r) =
P(X = 4) =
P(X = 4) =
P(X = 4) =
On solving the above eqn, we get:
P(X = 4) = 0.2344
Therefore, the probability of getting exactly 5 heads is 0.2344
