The diameter of circle whose perimeter is 8.8 cm is ___________. (π = $$\frac{22}{7}$$​)

Correct option is A

Given:

The perimeter (circumference) of the circle = 8.8 cm

$$\pi = \frac{22}{7}$$​

Formula Used:

Diameter $$= \frac{\text{Circumference}}{\pi}$$​

Solution:

Diameter = $$\frac{8.8}{\frac{22}{7}} = \frac{8.8 \times 7}{22} = \frac{61.6}{22} = 2.8 \, \text{cm}$$​

The diameter of the circle is 2.8 cm.
