Question

the sum of the circumference and diameter of a circle is 116 cm find its radius.
step by step

answer-14 ​

Answer 1

Answer:

14 cm

Step-by-step explanation:

C + D = 116 cm

2pie r + 2r = 116

44r/7 + 2r = 116

(44r + 14r)/7 = 116

58r = 116 × 7

r = (116 × 7)/58

= 14 cm Ans...

Answer 2

Circumference of circle = 2πr

Diameter of a circle = 2r

Now, Sum of diameter and circumference = 2πr + 2r = 116

=> 2r(π + 1) = 116

=> r(22/7 + 1) = 58.

=> r (29/7) = 58

=> r = 7 × 2

=> r = 14 cm.
