12.56
Step-by-step explanation:
The formula for finding the area of a circle is π*r²
to get the radius you half the diameter.
half of 4 is 2 then you square the radius which gets you to 4 again
then multiply 4 by 3.14 or PI
after you do that you should get the answer 12.56

A = 4pi or approximately 12.56
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We need to find the diameter
r = d/2
r = 4/2 = 2
A = pi (2) ^2
A = pi (4)
A = 4pi
We can approximate pi by 3.14
A = 3.14*4 = 12.56
