Question

Circle m has a radius of 4 cm. Circle p has a radius of 6 cm. what is the approximate diffrence between the area of the two circles

Answer 1

62.8 cm²

Explanation:

A₁ = π·r₁² = 3.14ₓ16cm² = 50.24 cm²

A₂ = π·r₂² =3.14ₓ36cm² = 113.04 cm²

A₂ - A₁ = 113.04cm² - 50.24cm² = 62.8 cm²

Answer 2

Approximately 63 cm²

Explanation:

pi × (r1² - r2²)

3.14 × (6² - 4²)

62.8 cm²

Approximately 63 cm²
