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

Answer:

8.3

Step-by-step explanation:

Given,

Circumference of the circle = 52 cm

Therefore ,

By the problem,

$= > 2\pi r = 52$

$= > 2 \times 3.14 \times r = 52$

$= > r = \frac{52}{3.14 \times 2}$

=> r = 8.2802547771

Rounded to nearest tenth,

=> r = 8.3 (Ans)
