a) The area of a circle is given by the formula:


A=(\pi* d^2)/(4)

Where A is the area, π=3.14 and d is the diameter=8 ft.

By replacing values:


A=(3.14*(8ft)^2)/(4)=(3.14*64ft^2)/(4)=50.24ft^2

b) The circumference of a circle is given by:


C=\pi* d

Where C is the circumference, π=3.14 and d is the diameter=8 ft.

By replacing values:


C=3.14*8ft=25.12ft
