Area = pi*r^2
r(radius) = diameter/2
24 cm/2 = 12 cm radius
Area = pi(12 cm)^2
~ 452 sq cm
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
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 the circle: pi*38 squared = 1444*pi square feet
if you double the radius (or diameter) , you get four times the area. area of a circle = pi * radius squared
There is no such unit of measurement as a diameter. A diameter is the distance across something - which can be as big or as small as desired.
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
929.03 square centimeters.
176.71443 The formula is .7854 times the diameter squared, or pi times the radius squared.
