2nd one in the first row is correct
answer: 25\pi\ ft^2 (first option)
the formula for calculate the area of a circle is the one shown below:
where r is the radius of the circle.
xy is the diameter. then the radius is:
substitute values into the formula shown above. therefore, the area of the circle is:
a=(5ft)^2\pi \\a=25\pi\ ft^2
~ i think hope dis
