A bakery sells a giant decorated cookie for birthdays. The area of the cookie is about 113 square inches. What is the circumfere

umka21 [38]

Answer:

38 inches

Step-by-step explanation:

The cookies is in the shape of a circle. The formula for the area of a circle is:

$A=\pi r^2$

Where r is the radius

The area is given as 113, so we can find the radius:

$A=\pi r^2\\113=\pi r^2\\r^2=\frac{113}{\pi}\\r=\sqrt{\frac{113}{\pi}} \\r=5.997$

We need to find the circumference, which has the formula:

$C=2\pi r$

Where r is the radius (We got r = 5.997)

We substitute and find:

$C=2 \pi r\\C = 2 \pi (5.997)\\C=37.68$

So, the circumference is 37.68 inches.

Rounded to nearest inch, that would be:

38 inches

If someone offers you a lottery ticket that has a 25 percent chance of winning $100, a 50 percent chance of winning $200, and a

g100num [7]

Answer: $375

Step-by-step explanation:

Given : The probability of winning $100 : P(100)= 0.25

The probability of winning $200 : P(200)= 0.50

The probability of winning $1000 : P(1000)= 0.25

Now, the the expected value of that lottery ticket is given by :-

$P(100)\times 100+P(200)\times200+P(1000)\times1000\\\\=0.25\times100+0.50\times200+0.25\times1000\\\\=375$

Hence, the the expected value of that lottery ticket =$375
