Question

*5. The radius of a circle increased by 1 cm then the ratio of the new circumference to the new diameter is
a)pie+2
b)pie+1
c)pie
d)pie-1/2​

Answer 1

Answer:

c)pie

Step-by-step explanation:

Let radius of circle =r,

According to question, radius of circle is increased by 1 unit.

Then, radius of circle r+1

Now, diameter of circle is D=2(r+1)

And Circumference of circle C=2×π×radius =2×π(r+1)

Now, ratio of circumference and Diameter of the circle,

C/D=2π(r+1)/2(r+1)=π/1

C:D=π:1

Hence, (c) pie or π is the answer.
