The diameter of a circle is 112 cm. What is the circumference of this circle? [Use π = $\frac{22}{7}$]
Answer & explanation
Correct answer: option 4
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
