Substitute r = 6.2 into the equation for area of a circle.

The equation for area a circle is #A=pi*r^2#

#120.7628#

The general equation for any circle is #pir^2 # where #r# is the radius.

Note #r^2 = rxxr #

Hence here #r = 6.2 #

#=> pir^2 = pi * 6.2^2 #

#=> pi * 38.44 #

# = 120.7628 # to 4 d.p
