Question

Two Circles have the same center. The Radius of the large circle is five units larger than the small circle. find the difference in both's circumfrence.



( Warning , only correct and right answers ,i will report all waste answers)

please needed help me , i wamt to understand​

Answer 1

$\huge \underline \mathbb {SOLUTION:-}$

Radius of smaller circle = x

Radius of larger circle = x + 5

Circumference = 2r

Circumference S = 2Tx

Circumference L = 21 (x+ 5) = 2TX + 10TT

Difference =L -S = 2Tx + 10TT - 2TTX = 10T

Answer 2

Answer:

Radius of inner circle = r

Radius of outer circle = r+5

Circumference of inner circle = 2πr

Circumference of outer circle = 2π(r+5)

Difference between both circumferences =

2π(r+5)-2πr

= 2π(r+5-1)

= 2π(r+4) units
