• A. 80 cm
• B. 88 cm
• C. 66 cm
• D. 44 cm

Answer 1

The correct option is B 88 cm

Circumference of a circle is given by $\pi d$ where, d is the diameter of the circle.
Given, d = 28 cm
Circumference $=\pi \times 28$
$=\frac{22}{7}\times 28$
$=88$ cm
Hence, the circumference of the circle is 88 cm.
