The radius of a circle is 13 meters. What is the circle's circumference?

Mathematics
1 answer:
Vlad [161]2 years ago
8 0

Answer:

The circumference of a circle is calculated by multiplying the diameter of a circle by π (π × d) . The formula to calculate the circumference of a circle is usually written c = πd .

Step-by-step explanation:

Pi is a number that is approximated by 3.14, or 22/7. It is the ratio of the circumference to the diameter of any circle. This ratio can be rearranged to find circumference of a circle by multiplying pi times diameter.

I hope this helps.

R/12=1 9/10<br><br> Solve for R.
Marianna [84]
Let's first turn 1 9/10 into an improper fraction, which is 19/10

so if R/12 equa;s 19/10, cross multiply

10r equals 228

divide both sides by 10, you get r= 22.8

The American Veterinary Association claims that the annual cost of medical care for dogs averages $100 with a standard deviation
Taya2010 [7]

Answer:

The probability that the cost for someone's dog is higher than for the cat is 33.2%.

Step-by-step explanation:

With the data given, we know that the difference in cost of medical care of dogs and cats have a normal distribution with μ=-20 and σ=46.

To know the probability of the cost for the dog is higher than the cat, we have to calculate the probability of P(d>0).

Then we have to calculate z, and look up in a standarized normal distribution table.

Calculate z:

z=\frac{X-\mu}{\sigma}=\frac{0-(-20)}{46}=\frac{20}{46}=   0.4348

The probability of the difference being higher than 0, we have:

P(d>0)=P(z>0.4348)=0.33185

We can say that the probability that the cost for someone's dog is higher than for the cat is 33.2%.

The distance between two schools,A and B is 2 km.A market is situated a third of the distance from A to B.How far is the market
bekas [8.4K]

Answer:

\frac{4}{3}

Step-by-step explanation:

Find distance between B and market: |B-M|=|M-B|

Distance between A and B: |A-B| = 2 , call this equation (1)

Distance between A and market |A-M| = \frac{1}{3} |A-B|=\frac{2}{3}, call this equation (2)

Solve (1) - (2)

|A-B-A+M| = 2-\frac{2}{3} \\|M-B|=|B-M|=\frac{4}{3}
