Question

find diameter radius circumference and area the value of area 616 CM square ​

Answer 1

Answer:

radius=14 and circumference =88

Step-by-step explanation:

Answer 2

Answer:

Here the area is 616 cm square. And as we know the area of a circle is pi*(radius of that circle)^2. If we think r as the radius of that circle than

Step-by-step explanation:

⇒$pi *r^{2}$=616

⇒$r^{2}$=616/pi

⇒r²=616/3.1416    [as pi=3.1416]

⇒r=√196.08

⇒r=14.003

As we know the circumference of a circle is 2*pi*r.

So,circumference ⇒2*pi*r=2*3.1416*14.003=87.98
