A circle that has a radius of 4.6 centimeters has an area of 66.5 square centimeters.
6647.61cm2
diameter = double the radius = 48 cm
As area = pi * radius2, the radius is given by radius = sqrt(area /pi) radius = sqrt(6644.24 / pi) = 46 with pi = 3.14
The area of a cirle is: PI * r2 Where "r" is the radius, and PI is approximately 3.14. Hint: A radius is half of the diameter.
Radius = 1/2 of the diameter = 46 inches.
Diameter of a circle = 2*radius Diameter of a circle = circumference/pi
Circumference of the circle: 2*23*pi = 46*pi inches
6.78233......(Square root of 46)
In a rectangle, the area is calculated by multiplying length x width. If (for example) both length and width are in centimeters, the area will be in square centimeters.
There are approximately 116.84 centimeters in 46 inches.
1 meter = 1 hundred centimeters 46 meters = 46 hundred centimeters
A rectangle 8 centimeters by 15 centimeters has a perimeter of 46 centimeters (2l + 2h) and an area of 120 centimeters (l * h).
