Find the area of a circle with diameter 31.6 cm, both in terms of p and to the nearest tenth. Use 3.14 for p.
Your answer:
A = 249.64p cm2» 783.9 cm2
A = 63.2p cm2» 198.4 cm2
A = 31.6p cm2» 99.2 cm2
A = 998.56p cm2» 3135.5 cm2

Answer:

Option (1)

Step-by-step explanation:

Formula to get the area of a circle is given by,

Area = πr²

Here r = radius of the circle

Since, Radius of a circle = [tex]\frac{\text{Diameter}}{2}[/tex]

Therefore, Radius of the circle with diameter = 31.6 cm will be,

Radius = [tex]\frac{31.6}{2}[/tex]

            = 15.8 cm

Now Area of the circle = π(15.8)²

                                      = 249.64π cm²

                                      = 783.87 cm²

                                      ≈ 783.9 cm²

Therefore, Option (1) will be the correct option.
