Circumference of circle= 2*pi*r

You need to figure out the radius from the diameter. The radius is half of the diameter. Therefore, the radius in this problem is 4.5.

Since you are rounding pi to a whole number, 3.14 would be converted to 3. 

This is now the equation: 2*3*4.5

27 cm

According to police sources, a car with a certain protection system will be recovered 87% of the time. Find the probability that
WITCHER [35]

Answer: 0.01145

Step-by-step explanation:

We use Binomial distribution , where the probability of getting x successes in n trial is given by :-

P(x)=^nC_xp^x(1-p)^{n-x} , p = probability of getting each success in each trial.

As per given

The proportion that a car with a certain protection system will be recovered= p=0.87

n= 8

Let x be the number of cars will be recovered.

Then, the probability that 4 of 8 stolen cars will be recovered:

P(X=4)=^8C_4(0.87)^4(1-0.87)^{8-4}

=\dfrac{8!}{4!(8-4)!}(0.87)^4(0.13)^4\\\\= 70(0.57289761)(0.00028561)\\\\=0.0114537700474\approx0.01145

Hence, the required probability is 0.01145.

 Independent variable: x
 Dependent variable: y
 For x = -1:
 </span>y = (- 1) ^ 2 = 1 &#10;
<span> For x = 1:
 </span>y = (1) ^ 2 = 1 &#10;
<span> We observe that the independent variable can only obtain one result.

jonny [76]

Answer: 512 times

Step-by-step explanation:

$$Volume of Solid $A=5632 \mathrm{~cm}^{3}$ \\Volume of Solid $B=11 \mathrm{~cm}^{3}$.\\Divide volume of Solid $A$ by volume of Solid $B$.\\Volume of Solid A\\Volume of Solid $B$\\

\frac{5632 \mathrm{~cm}^{3}}{11 \mathrm{~cm}^{3}}=512\\\\$$\text{Therefore, Solid $A$ is 512 times larger thm Solid B}
