Question

if the circumference of a circle is 52 cm, what is the radius? round to the nearest tenth. PLESE HELP I DONT HAVE THAT MUCH TIME :(

Answer 1

8.3

Explanation:

Given,

Circumference of the circle = 52 cm

Therefore ,

By the problem,

`= > 2\pi r = 52`

`= > 2 * 3.14 * r = 52`

`= > r = (52)/(3.14 * 2)`

=> r = 8.2802547771

Rounded to nearest tenth,

=> r = 8.3 (Ans)
