The area of the circle whose circumference is equal to the perimeter of the square is 38.47 squared units.

<h3>What is circumference and area of the circle?</h3>

Circumference of the circle is the length of its boundary. It can given as,

P=2\pi r

The area of the circle is the space occupied by it. It can be given as,

A=\pi r^2

Here (<em>r</em>) is the radius of the circle.

A square has a side that measures 5. 5 units. The perimeter of the square is the equal to the 4 times of its side. Thus its perimeter is,

P=4\times5.5\\P=22\rm\; units

The circumference of the circle is equal to the perimeter of the square. Thus the radius (<em>r</em>) of circle is,

P=2\pi r\\22=2\times\pi r\\r\approx3.5\rm\; units

The area of this circle is,

A=\pi r^2\\A=3.14\times (3.5)^2\\A=38.465\\A\approx 38.47\rm\; units^2

Hence the area of the circle whose circumference is equal to the perimeter of the square is 38.47 squared units.

kicyunya [14]
To find the circumference of the circle you need to do dπ. 22×π is 22π. That equals approximately 69.12. Since he walks around it 5 times, 69.12×5 is 345.6 yards.

How do I solve question 13 and 14?
xxMikexx [17]

Answer:

13. 13 or 17 (not sure about this, sorry)

14. 28

Step-by-step explanation:

13.

a_{n} = \{a_{0}, a_{1}, a_{2}, a_{3}, a_{4}, ... \} \\

if counting the sequence from a_{0} then a_{4} is 17, but if

a_{n} = \{a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, ... \} \\

counting from a_{1}, then a_{4} is 13.

14.

a_{10} = 1 + 3(10 - 1) = 1 + 3*9 = 28

If a person tosses a coin 23 times, how many ways can he get 11 heads
EastWind [94]

Tossing a coin is a binomial experiment.

Now lets say there are 'n' repeated trials to get heads. Each of the trials can result in either a head or a tail.

All of these trials are independent since the result of one trial does not affect the result of the next trial.

Now, for 'n' repeated trials the total number of successes is given by

_{r}^{n}\textrm{C}

where 'r' denotes the number of successful results.

In our case n=23 and r=11,

Substituting the values we get,

_{11}^{23}\textrm{C}=\frac{23!}{11!\times 12!}

\frac{23!}{11!\times 12!}=1352078

Therefore, there are 1352078 ways to get heads if a person tosses a coin 23 times.
