It is given that the area of the pizza is
[tex] A = 625 \pi [/tex]
And pizza is of circular shape. And the formula of area of circle is
[tex] Area = \pi r^2 [/tex]
Using the given value of area, we will get
[tex] 625 \pi = \pi r^2
\\
625 = r^2 [/tex]
Taking square root on both sides,
[tex] \sqrt{625} = r
\\
r = 25cm [/tex]
And diameter is double of radius. THerefore diameter is 50 cm .
