Answer:
E. 9 times bigger
Step-by-step explanation:
Here's a made up example. Let's say that the radius of a circle is 5.
Circumference = 2πr
2π(5) = 31.42
Area = πr²
π(5)² = 78.54
If the circumference of a circle triples, that means that the radius also triples. So, the new radius is 15.
C = 2πr
C = 2π(15)
C = 94.26
A = πr²
A = π(15)²
A = 706.86
94.26 ÷ 31.42 = 3 ⇒ The circumference tripled.
706.86 ÷ 78.54 = 9 ⇒ The area is 9 times bigger.
Hope this helps. :)
