Answer:

Draw a circle with center #(2,5)# and radius #10#

Explanation:

The general equation for a circle centered at #(color(red)(h),color(blue)(k))# with radius #color(green)(r)# is:
#color(white)("XXX")(x-color(red)(h))^2+(y-color(blue)(k))^2=color(green)(r)^2#

#(x-color(red)(2))^2+(y-color(blue)(5))^2= color(green)(10)^2 (=100)#
is in this form.
graph{(x-2)^2+(y-5)^2=100 [-18.53, 27.07, -7.23, 15.57]}
