Formula to find the area of circle is:
a=πr² Where a= area and r= radius of the circle.
Given area: a=2,826 square centimeters.
So, plug in a=2,826 in the above equation to get r.
2826=πr²
[tex] \frac{2826}{\pi} = \frac{\pir^{2}}{\pi} [/tex] Dividing each sides by π.
[tex] \frac{2826}{3.14} =r^{2} [/tex] Since π=3.14
900=r²
√900=r
r=30
Since the diamter is twice the radius.
Hence, diameter= 2*30= 60.
So, the diameter of the circle is 60 centimeters.
900=
