Question

What is the approximate area of the circle shown below? 16 cm

Answer 1

201.143 (approx.) cm²

area of circle = (pi)x(radius)^2

= 22/7 x (8)^2

=22/7 x 64

= 1408/7

= 201.142857143

= 201.143 cm^2 (approx.)

Answer 2

the approximate area of circle is 201 cm²

D is the correct option.

Explanation:

From, the given figure, the diameter of the circle is 16 cm.

The radius is half of the diameter.

Hence, the radius of circle is 16/2 = 8 cm

The area of a circle is given by

`A=\pi r^2`

Substituting the value of r and π

`A=3.14(8)^2\\\\A=200.96\\\\A\approx201`

Therefore, the approximate area of circle is 201 cm²

D is the correct option.
