Question

find the diameter of circle whose circumference is 37.7​

Answer 1

Step-by-step explanation:

hey mate

we know that diameter is double of radius.

given,

circumference=37.7

solution

$circumference = 37.7 \\ 2\pi \: r = 37.7 \\ r = \frac{37.7 \times 7}{2 \times 22} \\ \\ = > r = \frac{263.9}{44} \\ \\ = > r = 5.9(approx \: 6) \\ \\ now \: we \: can \: find \: diameter \\ \\ 2 \times 6 = 12 \: is \: diameter$

Answer 2

Answer:circumference =

$2\pi r$

37.7=

$2\pi r$

$377 \div 10 = 2\pi r$

377÷10×2=22÷7

377×7÷10×2×22=r

6.47=r,d=6.47×2=12.94 ans
