Question

surface area of wooden table top of diameter 1.4 m is​

Answer 1

Answer:

πr^2 =3.14xo.7^2 = 1.54m2

Answer 2

Question:

Calculate the surface area of a circular wooden table of diameter 1.4m.

Answer:

To calculate the surface area of any circular plain,we have to calculate the radius of that circular area.

Radius = Diameter/2

Radius = 1.4/2 = 0.7 m.

Now the mathematical formula to calculate circular surface is ;

πr² = 22/7 × (0.7)² = 22/7 × 0.49 = 1.54 m² .

So the surface area of that table top is 1.54 m² (answer)
