Answer:

50π cm²

Explanation:

The radius of the larger circle is 10 cm, so its area is ...

A = πr² = π(10 cm)² = 100π cm²

The area of each smaller circle is ...

A = π(5 cm)² = 25π cm²

Then the shaded area is ...

shaded = large circle - 2 × small circle

shaded = 100π cm² - 2(25π cm²) = 50π cm²
