Answer 2

Answer:

The area of the disc is 314 cm²

Explanation:

Given :

• Radius of circular disc (r) = 10 cm

• Use π = 3.14

Find :

• The area of the disc in cm²

Solution :

★ As we know that

Formula of area of circular disc

Area of circular disc = π r²

⇒ 3.14 × 10 × 10

⇒ 3.14 × 100

⇒ 314

⇒ 314 cm²

Therefore,

The area of the disc is 314 cm²
