Answer 1

That’s how you get the answer

Answer 2

Answer:

B is correct option.

Step-by-step explanation:

The image of button is 5 times the button's actual size.

The diameter of image is 6 cm

We are given the diameter of image. It would be shape of circle.

Let the actual size of circle is x and Diameter be d cm

Size of image = 5x

Size of circle is directly proportional to their diameter.

Therefore,

$\dfrac{5x}{6}=\dfrac{x}{d}$

Now we will solve for d

$d=\dfrac{6}{5}\text{ cm}$

Thus, B is correct option.
