The area of a circle is,

So pi times the radius squared.
~~
To find the radius we half to divide the diameter by 2 since the radius is half of the diameter.
The diameter is the line that passes through the the center of the circle going from one side of the circle to the other which is 4 in this case.
Half of 4 is 2 meaning 2 is our radius.
~~
Plug in the numbers and get,

Answer:
60% chance of rain
Explanation;
A way you can get the percentage would be putting the fraction in your calculator. For example here it is 3/5, when the denominator is 5 you can say 20% for each whole number.
1/5 = 20% chance
2/5= 40% chance
3/5=60% chance
4/5= 80% chance
5/5= 100% chance
The answer would actually be A
F(x)=3x^2+4x
G(x)=2x^2-x+1
The two x^2 items are both positive and are added together to be 5x^2
The two x items would be added together to get 3x cause of the -x
Then +1 is just +1
Making the equation 5x^2+3x+1
If we were subtracting you would be absolutely correct, but since we are adding would go the opposite direction.
I hope this helps!
