Answer:
The larger circle has an approximate area of 314 cm²
Explanation:
As you can see by the diagram, the white circle is twice as wide as the grey circles. That means that its radius is also twice theirs.
The grey circles have a radius of 5cm, so the larger has a radius of 10cm.
The radius of a circle is equal to πr², where r is the radius of the circle. So the larger circle's radius is:
π × 10²
≈ 3.14 × 100
= 314.
So the larger circle has an approximate area of 314 cm²
