The general equation for the area of a circle is π*r2, where r is the radius of the circle, and π is pi, which is approximately 3.14159. The diameter of a circle is how far it is from one side of the circle to the other, and the radius is how far it is the from edge to the center, thus the radius is half the diameter. Therefore the area is π*(92) ~ 254.47

How do measure the area and perimiter of circle?
OK, SO to find the area of a circle, you find the radius (half of the diameter), and fit it into the equation πr2=A where r equals radius and A = area. The perimeter of a circle is π multiplied by the diameter. π is ≈ 3.1415296.
Find the Lateral Area of a cylinder with diameter of 12 cm and a height of 20 cm?

How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
How do you find radius if you have the circumference or diameter or area?
circumfrence: divide it by π (3.14). Diameter: divide by 2. area: find diameter and divide by 2.
How do you find diameter of a circle with the area of 58.69?
Diameter is 8.64444
How to find the area of a circle?
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
Find the surface area of a cylinder with d equals 12 in h equals 14 in?
Total surface area including the two end pieces: (2*pi*radius2) + (pi*diameter*height) Area = 240*pi square inches
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
How do you find the area using the diameter?
I assume that you are referring to the area of a circle. You divide the diameter in half to find the radius and then you put it into the formula.
