Answer:

12.686cm

Step-by-step explanation:

By using pythagoras, we can find CB.

We know that a^2+b^2=c^2

Therefore, 12^2-6^2=CB^2

CB=\sqrt{108} (it has to be positive since it is distance)

now we look at triangle BCD and use SOH CAH TOA.

Sin55=CB/CD\\Therefore, CD= 12.686

How tall would one million pennies be in centimeters.And how do you know
Vikki [24]
One US-penny is 19 mm in diameter.

One British-penny is 20.3 in diameter.

We can make an accurate measurement of the diameters, or research on the internet.


1 milion US_pennies are

1,000,000*19 mm = 19,000,000 mm = 1,900,000 cm tall, since 1cm=10mm


1 milion British_pennies are 

1,000,000*20.3 mm = 20,300,000 mm = 2,030,000 cm tall, since 1cm=10mm
