Question

The two circle with the same centre.the radius of the larger circle is 10 cm and the radius of smaller circle is 4 cm. 1. The area of larger cicle.2.the area of smaller circle

Answer 1

1.
Area of larger circle =  \pi R²
Area of larger circle = 22÷7×(10)²
Area of larger circle = 3.1428×100
Area of larger circle = 314.28 cm²

2.
Area of smaller circle =  \pi r²
Area of smaller circle = 22÷7×(4)²
Area of smaller circle = 3.1428×16
Area of smaller circle = 50.28 cm²
