Answer 1

Answer:

141.43 cm²

Step-by-step explanation:

Question:

A circle with radius of 6 cm, sits inside a circle with radius of 9cm.

What is the area of the shaded region?

Round your final answer to the nearest hundredth.

Area of the circle with radius 6 cm:

Area = πr²

Area = π(6)²

Area = 36π cm²

Area of the circle with radius 9 cm:

Area = πr²

Area = π(9)²

Area = 81π cm²

Area of the shaded region:

Shaded Region = 81π - 36π

Shaded Region = 45π

Shaded Region = 141.43 cm²

Answer: 141.43 cm²
