Answer:
Die: 16. 2/3%
Coin: 50%
Step-by-step explanation:
Well rolling a 4 on a 6 sided die is 1/6.
To make that a percent we first make it a decimal.
1 ÷ 6 = .16666 repeating
To make this a percent we move the decimal place 2 times to the right.
16.2/3%
The chance of flipping a heads on a fair sided coin is 50% because there are two sides with a 50/50 chance of being either.
<em>Thus,</em>
<em>for rolling a 4 on a 6 sided die there is a 16.2/3% chance and a 50% for flipping a heads on a 2 sided coin.</em>

Hey there!
Formula for the area of a circle: 
Formula for the radius of a circle: 
First, let's divide the diameter by 2 in order to find the radius.
16/2 = 8
Next, we'll plug our values into the formula (found above).
A = pi x 8^2
A = pi x 64
A = 64pi^2 or A = 201.1cm^2
Hope this helps!! :)
