a.12.1in
b.12.6in
c.25.1in
d.50.2in
To find the circumference of a circle, use the formula:
C = 2πr
Where C is the circumference, π (pi) is approximately 3.14, and r is the radius of the circle. Given that the radius is 4 inches:
C = 2(3.14)(4)
C = 6.28(4)
C = 25.12
Rounding to the nearest tenth, we get 25.1 inches. So the answer is option C. 25.1 in.
