Question

What is the diameter of a circular field whose area is 616cm^2​

Answer 1

Answer:

28

Step-by-step explanation:

area of a circle

$\pi{r}^{2}$

616=3•142×r×r

616/3•142=r^2

196=r^2

r=√196

r=14

d=2r

d=2×14

d=28

Answer 2

Answer:

28cm

Step-by-step explanation:

$d=2\sqrt{\frac{A}{\pi}} =2\sqrt{\frac{616}{\pi} }$≈$28.00563cm$

rounding 28.00563 to 28.

So hence, your answer is 28cm
