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

How many ways can the words in d-r-a-g-o-n-f-l-y be arranged
GarryVolchara [31]

Answer:

362880 ways

Step-by-step explanation:

The word dragonfly has 9 different letters.

So, to find how many ways this word can be arranged, we just need to calculate the factorial of 9:

First letter has 9 possibilities

Second letter has 8 possibilities (one used)

Third letter has 7 possibilities (two used), and so on.

So the number of ways is:

9*8*7*6*5*4*3*2*1 = 362880 ways
