Question

the radius of the larger circle is 10cm. the radius of the smaller circle is 5cm. what is the approximate area of the shaded region?

Answer 1

Explanation:

Area of the shaded region = Area of the Large circle — Area of the Small circle

A = πR²–πr²

A = π(R²—r²)

A = π(R+r)(R—r)

A = π(10+5)(10—5)

A = π(15)(5)

A = 75πcm² ✓✓✓√√
