Question #10426

Find both the circumference and the area of the circle whose equation is (x-2)^2 + (y-3)^2=64. Approximate your answer to the hearest hundreth of a unit.

Expert's answer

circumference = 2*pi*r

area=pi*r^2

where r - radius of the circle

from

equation radius is equal to sqrt(64)=8

so

circumference=2*pi*8=50.27

area=pi*64=201.06

area=pi*r^2

where r - radius of the circle

from

equation radius is equal to sqrt(64)=8

so

circumference=2*pi*8=50.27

area=pi*64=201.06
