Question

The difference between the circumference and radius of a circle is 37 cm. Find the circumference of that circle.


I promise to mark the brainliest for the best answer.

Answer 1

Answer:

44 Cm

Step-by-step explanation:

Radius of Circle = R

Circumference of Circle = 2π R

According to question...

(2πR - R) = 37

(2π-1) R = 37

R = 7 cm

Now, Circumference = 2 π R = 2*π*7 = 44 cm.

Answer 2

Hᴇʀᴇ's Yᴏᴜʀ Aɴsᴡᴇʀ:-

Lᴇᴛ r ʙᴇ Tʜᴇ Rᴀᴅɪᴜs ᴏғ Cɪʀᴄʟᴇ.

Dɪғғᴇʀᴇɴᴄᴇ Bᴇᴛᴡᴇᴇɴ Cɪʀᴄᴜᴍғᴇʀᴇɴᴄᴇ Aɴᴅ Rᴀᴅɪᴜs ᴏғ Tʜᴇ Cɪʀᴄʟᴇ = 37 ᴄᴍ

Cɪʀᴄᴜᴍғᴇʀᴇɴᴄᴇ ᴏғ Cɪʀᴄʟᴇ = 2πr

= 2 × 22/7 × r

= 44/7 × r

Nᴏᴡ,

Dɪғғᴇʀᴇɴᴄᴇ Bᴇᴛᴡᴇᴇɴ Cɪʀᴄᴜᴍғᴇʀᴇɴᴄᴇ Aɴᴅ Rᴀᴅɪᴜs ᴏғ Cɪʀᴄʟᴇ = 2πr - r

37 = 44/7 × r - r

37 = r ( 44/7 - 1 )

37 = r ( 44 - 7 )/7

37 = 37/7 × r

37 × 7/37 = r

r = 7 ᴄᴍ.

Nᴏᴡ, Cɪʀᴄᴜᴍғᴇʀᴇɴᴄᴇ ᴏғ Cɪʀᴄʟᴇ = 44/7 × r

= 44/7 × 7

= 44 ᴄᴍ.
