Answer:

The area is #196pi#, or #615.752160# when evaluated to 6 decimal places.

Explanation:

There is an equation for the area of a circle:

#A=pir^2#

Where #A# is the area and #r# is the radius. #pi# is #pi#, it is its own number. Plugging in the radius stated we can evaluate:

#A=pi(14)^2#

#color(green)(A=196pi)#

If we write out #pi# and evaluate with an (un)reasonable amount of decimal places:

#pi~=3.1415926536#

#A=196xx(3.1415926536)#

#color(green)(A~=615.752160)#

Answer:

The area of the circle is #615.75# units#""^2#

Explanation:

Area of a circle is defined with this equation: #A=pir^2#

When #r=14#,

#A=pi(14)^2#
#color(white)(A)=615.75# units#""^2#
