Question
What is the diameter of 11.94 cm circumference
Answer:
Soln,
We know that diameter = * 2 radius
radius = 11.94/2= 5.97 half of diameter and when you multiply with 2 ,Then it comes 11.94cm
Now
Step-by-step explanation
Circumference = 2πr
11.94 = 2*22/7*r
11.94 = 6.28r
r= 11.94/6.28
therefore, r= 1.90 cm
Now
We know that diameter = * 2 radius
diameter = 1.90*2 = 3.80 cm
answer checking,
Circumference = 2πr
c= 2*22/7*1.90
therefore c = 11.94 cm
ans proved
plz mark me brainliest and thanks
have a good day ahead ; )
