Question

would someone mind helping me with a few questions? :)

Answer 1

to find the area of a circle you need to know that
A-pi ^2
and to find the circumfrence of a cirlce
C=2 pi a
what i dont know is what information i need to obtain to find either the area or circumfrence of a circle.

Answer 2

To find area is to take half the diameter of any circle (r), times that by itself (r^2), times pi (3.14).

Finding the circumference is just taking the whole diameter and times-ing that by pi. so:
\[A= 3.14* r^2\]
\[C=3.14*D\]

Answer 3

Concepts to remember.
• The Circumference is the area around the outside of the circle.
• The Radius is a straight line from the center of the circle and the endpoint lies on the circle.
• The Diameter is a straight line through the center of the circle and both endpoints lie on the circle. Therefore the Diameter is twice the length or distance of the radius.
• pi π symbolizes the ratio -- the relationship with respect to relative size of the circumference of circle to its diameter. The numrical value of π is 3.14

Answer 4

would that be the information i need to obtain?

Answer 5

r is radius or half of the cirle while d is diameter of the whole circle

Answer 6

yes
