Question

The circumference of a circle is exceeds by 18.4 by it's diameter Then find the redius of the circle.

Answer 1

Answer:

4.29

Step-by-step explanation:

let radius=x, diameter=2x

circumference=2x+18.4

also circumference=2×pi×r =2×pi×x

so. 2x+18.4=2×pi×x

x+9.2=pi×x

x+9.2=3.14x

2.14x=9.2

x=4.29
