Find the area of the circle from the given diameter. d= 4 ft
a 11.4 ft2
b 12.56 ft2
C 10.81 ft2
d 14.98 ft2

B is our answer 12.56

When finding area for circles we do

radius x radius x pi

Since we don't have the radius in the problem we have to figure it out but it wont be so hard knowing that the radius is half of the diameter so 4 ÷ 2 = 2 so 2 is our radius now we need tp square it in easier words multiply by itself so

2 x 2 = 4 then we just do 4 x pi!

So 4 x 3.14 = 12.56 So our answer is 12.56

Hope this helps!

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

definitely a. the others have almost all data points on one side of the line.
