Answer 2

Answer :-

153.86

Step-by-step explanation:

Formula:- 2^r

But, diameter is given. So, we need to convert diameter into radius.

Diameter = 2 r (radius)

We now have the formula to find radius from diameter so, we can find the radius easily.

Diameter given is 49 cm

49÷2= 24.5

Radius = 24.5 cm

2^r = 2×3.14×24.5

= 153.86

U can also take 22/7 as your pie. Here we have the radius in points so the problem will be easy.

Thank you. I think it will help you and it's correct:-)
