Area of circle: pi times 2.25 squared = 16 square units rounded
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
The formula to find Circumference is: C = Pi x D (Pi is 3.1416 and D is Diameter). Hence, 3.1416 x 45 = 141.372 cm Square centimeters (sq cm) are a measure of area. Circumference is measured in linear centimeters not square centimeters. The answer is 141.372 cm.The circumference of a circle is Î *d.The circumference of a circle with a diameter of 45 centimeters would be 45Î cm.
32cm, the radius is half of the diameter
It is: pi times 45 = 141.372 cm rounded to three decimal places
A 45-foot diameter circle has an area of 1,590.4 square feet.
Using 3.14 as Pi the area of circle is: 1589.6250000000002
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
area=pi r squared the r is the radius which is half of the diameter so area =pi mulitplied by 45 squared which is 6361.725124mm
Using 3.14 as Pi the area of circle is: 6358.500000000001
A=pi*radius2=pi*(diameter/2)2 A=pi*(45/2)2 = 1589.625 square feet if pi=3.14
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
The area (A) of a circle is A = π . r2 The diameter (D) is equal to D = r / 2 . Were r is the radius. If the diameter of the circle is 45 mm, and we divide it by 2. We will obtain the radius which is equal to 22,5mm: D = 45mm / 2 = 22,5mm If we square this radius the result is 506,25mm2: r2 = (22,5mm)2 = 506,25mm2 So the area of the circle of diameter 45mm is: A = 506,25mm2 . π = 1590,43mm2d
The idea is to multiply the diameter by pi.
