Question

The diameter of a circular park is 14 m. Find the perimeter of the park. Assume ($\pi$= $\frac{22}{7}$).

• A. 4.4 km
• B. 44 m
• C. 440 mm
• D. 4400 cm

Answer 1

Answer: (B), (D)

The correct options are
B

44 m

D

4400 cm

Given, the diameter of the circular park = 14 m.

Hence, radius = $\frac{14}{2}$ = 7 m.

Circumference of the circular park $=2\times \pi \times r=2\times \frac{22}{7}\times 7=44$ m.

$\therefore$44 m = 4400 cm [Since, 1m = 100 cm]
