Question

Find the area of the shaded circle.give your answer in 3 significant numbers​

Answer 1

116.113 cm²

Explanation:

Area of a circle = πr²

Shaded area = External area - Internal area

= π × 6.5² - π × 2.3²

= π × (42.25 - 5.29)

= π × 36.96 = 116.113 cm²

Answer 2

116 cm²

Explanation:

The area of a circle = πr² ← r is the radius

shaded area = external area - internal area

= π × 6.5² - π × 2.3²

= π( 42.25 - 5.29)

= π × 36.96 ≈ 116 cm²
