Question

Calculate the area of a circular tabletop whose diameter is 1.2 meters. Round to

the nearest hundredth square meter.

Answer 1

• Diameter=1.2m
• Radius=1.2/2=0.6m

`\\ \sf\longmapsto Area=πr^2`

`\\ \sf\longmapsto Area=3.14(0.6)^2`

`\\ \sf\longmapsto Area=3.14(0.36)`

`\\ \sf\longmapsto Area=1.13m^2`

Answer 2

• 1.13 m²

Explanation:

Area of circle:

• A = πr² = πd²/4

Given:

• d = 1.2 m

Find the area:

• A = 3.14*1.2²/4 = 1.1304 ≈ 1.13 m² (rounded)
