The area of a circle can be calculated with the equation:
[tex]\text{area}=\pi\cdot r^2[/tex]
the radius (r) is the diameter/2 so
r=5/2=2.5
and
π=3.14
[tex]3.14\cdot(2.5)^2=19.625[/tex]
but they ask you to round it to the nearest hundredth, which means 2 numbers after the point, so the answer is:
area of the circle: 19.63
