Find the area and the circumference of a circle with diameter 6M

Area of circle = πr^2 or π(d/2)^2

Circumference of circle = πd

For a circle with diameter 6m this becomes

A ≅ 28.27m^2 and C ≅ 18.85m

Step-by-step explanation: The constant π ≅ 3.14159 is the ratio of the circumference of a circle to its diameter (or equivalently to twice it's radius).

C = πd = π2r.

That same value, π, is also the ratio of the the area of a circle to the square of its radius

A = πr2

Plugging the given diameter (or diameter divided by 2 for the radius) into these equations gives the required results.
