The diameter of a quarter is 2.5 cm. What is it’s circumference?
anastassius [24]

Answer:

7.85 cm

Step-by-step explanation:

The circumference of a circle can be found using the following formula.

c=\pi d

The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.

c=\pi *2.5 cm

Now, find the circumference.

- In terms of pi:

c=\pi *2.5 cm

c= (2.5)\pi  cm

c= 2.5\pi  cm

-Using 3.14 as pi

c=\pi *2.5 cm

c=3.14 *2.5 cm

c=7.85 cm

-Using 3.14159... as pi

c=\pi *2.5 cm

c=7.85398163 cm

A CD has a 5% chance of being a smash hit and profiting $5.2 million, a 50% chance of being a modest success and profiting $0.9
Zinaida [17]
The probability of profiting $5.2 million is 5% = 0.05

The probability of profiting $0.9 million is 50% = 0.5

The probability of breaking even, meaning no profit gain, is 45% = 0.45

Expected profit values of the CD is given by
(0.05×5.2) + (0.5×0.9) + (0.45×0) = 0.26+0.45+0 = 0.71 million
