Question

please tell the answer please I beg you​

Answer 1

Given

• Radius of small circle = 6 cm
• Radius of bigger circle = 20 cm

To Find

• Area of the ring

Solution

• To Find the area of ring first we need to find the area of small and big Circle

Area of small circle = πr²

Area of small circle = 22/7 × 6²

Area of small circle = 22/7 ×36

Area of small circle ≈ 113.1428 cm²

Area of big circle = πr²

Area of big circle = 22/7 × 20²

Area of big circle = 22/7 ×400

Area of big circle ≈ 1257.1428 cm²

Now,

Area Of Ring= Area Of Big circle - Area of Small Circle

Area Of Ring= 1257.1428 - 113.1248

• Area of Ring = 1144 cm²
