There is a round table in the park pavilion. How many square decimetres should I draw? {reserved for numbers 10 square decimeter}

1, painting area of desktop: (side area+a round surface+a ring)

3. 14×8×0.5+3. 14×(8÷2)? +3. 14×[(8÷2)? - 1? ]

= 12.56+50.24+47. 1

= 109.9(dm？ )

2. Paint the area of the supporting part: (Only paint the side area)

2×3. 14× 1×6 = 37.68(DM？ )

3. Area to be painted:109.9+37.68 =147.58 (DM? )
