Question:

The diameter of a circle is 112 cm. What is the circumference of this circle? [Use π = $\frac{22}{7}$]

Options:

256 cm

396 cm

416 cm

352 cm

Correct Answer:

352 cm

Explanation:

We have,

Circumference of a circle = 2πr

Given,

The diameter of a circle = 112 cm.

then, radius of the circle = $\frac{112}{2}$= 56

Circumference = 2 × $\frac{22}{7}$× 56= 2 × 22 × 8= 352 cm
