Step-by-step explanation:
The formula for the area of a circle is π*r^2, r being the radius or the half line in the circle, and the formula for the circumference is π*r*2, or π*d, or the diameter which is the line that goes all the way through like number 5. The radius is half the diameter.
Answer:
A =78.5 in^2
Step-by-step explanation:
The area of the circle is given by
A = pi r^2
A = pi * r^2
A = 25 pi
Using 3.14 for pi
A = 25 (3.14)
A =78.5 in^2
The answer to the question is... 12
