Question

A body is moving on a circular path of radius 7cm it complete its one round in 2s calculate distance

Answer 1

Answer:

44cm

Explanation:

2πr = 2 x 22/7 x 7

      = 44cm

PLEASE MARK ME AS BRAINLIST

Answer 2

Gɪᴠᴇɴ :-

• Radius (r) of circle = 7cm
• Time taken (t) to travel 1 round = 2 s

Tᴏ ғɪɴᴅ :-

• Total distance (d) travelled by body

sᴏʟᴜᴛɪᴏɴ :-

Now,

✞ According to Question :-

➠ Distance covered by body = Circumference of Circle

We know that,

➠ Circumference of Circle = 2πr

➠ 2πr = 2 × 22/7 × 7

➠ 44 cm

Hence,

➠ Circumference of Circle = 44 cm

Therefore,

• ➠ Total distance(d) covered by body = 44 cm
