Question

If the perimeter of a circle is 540, the radius of the circle will be
(a) 84.05
(b) 85.90 (c) 86.25
(d) 87.30
​

Answer 1

Answer:

(a) 84.05

Step-by-step explanation:

If the perimeter of a circle is 540, the radius of the circle will be 84.05

Answer 2

Answer:

perimeter of circle = 2πr

ie, 2πr = 540

solving it

πr=540/2

  = 270

22/7 x r = 270

22 x r = 270 x 7

22r =  1890

r =   1890/22

r =  85.9090909091

since option (b)  is correct
