The diameter of a circle is tripled. How does that affect the circumference? How does that affect the area? Explain.

Answer:The formula for the circumference is 2πr. If you triple the radius the formula would be 2π3r. the ratio between the two is 2π3r / 2π1r. 2π & r cancels out and you have 3/1 left. Therefore the answer is the circumference is tripled.

The fact that there is no exponential in the formula indicates that the proportional increase is lineal.

The Circumference is 2πr.

When the radius is x, the circumference is 2πx

When the radius is tripled, it becomes 3x, to the circumference will be 2π(3x) = 6πx.

Soooooooo the circumference will also be tripled.

Step-by-step explanation:hope this helps
