If the circumference of a circle with radius 7 is 43.96, what is the circumference when the radius is doubled to 14, using pi=3.14?

The relationship between a circle’s circumference and its radius is linear: circumference equals 2πr. Doubling the radius doubles the circumference. Using π = 3.14, with the radius now 14, the circumference is 2 × 3.14 × 14 = 6.28 × 14 = 87.92. Since the original circumference at radius 7 is 43.96, doubling the radius doubles the circumference to 87.92.
