Area = pi*82 = which is about 201 square inches to 3 s.f.
The diameter is 6 units.
Given the diameter of the circle, multiply it by π (approx 3.14159).
The perimeter of a cirlcle is its circumference which is: 2*pi*radius or diameter*pi
Area is proportional to the square of the linear dimensions.If diameter is tripled, area increases by a factor of (3)2 = 9 .
d * pi or 2 * r * pi Where d is diameter and r is radius and pi = 3.14159
You need to measure it with something flexible, like a string.If you know for sure it is a circle, it would be easier to measure the diameter, then multiply by pi.
"Diameter" is the distance all the way across the circle, through the center."Radius" is 1/2 of the diameter ... the distance from the center to the curvy part of the circle."Circumference" is the distance all the way aroundthe circle.
Diameter = Circumference / Pi Diameter = 16 / 3.14 Diameter = 5.095
