Area of circle: pi times radius squared
Centimeter is a measurement unit in the metric system. The diameter is not a measurement unit. The diameter of a circle is twice the length of the radius of the circle.
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius squared
A diameter is the size of a circle from edge to edge when measuring through the centre. Consequently, as a circle can be any size, there can be any number of centimetres in the diameter..
Area of a circle is PI times the square of the radius (half the diameter). 3.1415 x (7.5 squared) = about 176.7 square feet
Area of circle: pi times radius squared
Centimeter is a measurement unit in the metric system. The diameter is not a measurement unit. The diameter of a circle is twice the length of the radius of the circle.
Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius squared
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
Circumference of a circle = 2*pi*radius or pi*diameter Area of a circle = pi*radius squared
Area of the circle: pi*38 squared = 1444*pi square feet
A diameter is the size of a circle from edge to edge when measuring through the centre. Consequently, as a circle can be any size, there can be any number of centimetres in the diameter..
if you double the radius (or diameter) , you get four times the area. area of a circle = pi * radius squared
Area of a circle is PI times the square of the radius (half the diameter). 3.1415 x (7.5 squared) = about 176.7 square feet
The diameter of a circle is a straight line passing through the center of the circle and connecting two points on the circumference. The length of the diameter is equal to twice the radius of the circle. If we assume the diameter is 1 unit, then it would be equivalent to 1 centimeter. Therefore, there are 1 centimeter in 1 diameter.
176.71443 The formula is .7854 times the diameter squared, or pi times the radius squared.
929.03 square centimeters.
