Question

What is the diameter of a circle whose circumference is 11

Answer 1

Answer: 3.5

Step-by-step explanation:

circumference of a circle = 2πr

2πr = 11

2×22/7×r=11

∴r= (11×7)÷44

∴r= 7/4

∴diameter = 2×r = 7/2 = 3.5

Answer 2

Step-by-step explanation:

Given : Circumference ,c =11

c=2πr

11=2*22/7*r

r=11*7/2*22

r=7/4

so, diameter=7/4*2=7/2
