Question

find the space enclosed between two concentric circles of raddi 17cm and 11cm

Answer 1

Answer:

528 cm²

Step-by-step explanation:

Find the area of the circle with radius 17 cm:

Area = πr²

Area = π(17)² = 289π cm²

Find the area of the circle with radius 11 cm:

Area = πr²

Area = π(11)² = 121π cm²

Find the area enclosed:

Area = 289π - 121π 

Area = 168π

Area = 528 cm²

Answer:  528 cm²
