The circumference of a circle with a diameter of 45 inches is 141.37 inches.
A 45-foot circumference circle has an area of: 161.1 square feet.
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.

There are 45 degrees in 1/8 of a circle's circumference.
Radius is 45.
circumference = 2*pi*radius r = c/2*pi r = 6.28/2*pi r = 0.9994930426 units area of the circle = pi*r2 = 3.138408154 square units
For A+ 7.22The area of a sector of a circle is proportional to the angle at the center of the sector, with 360 degrees corresponding to the full circle. Therefore, the area of the total circle for which the problem is stated is 50 X 360/110 = about 163.6 square units. The area of a circle is also equal to pi multiplied by the square of the radius of the circle, so that the radius r of this circle equals the square root of 163.6/pi = about 7.217 units. The circumference of the circle is also twice the radius multiplied by pi = 45 units, to the justified number of significant digits (limited by "50").a+ 45.33
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.
A 45-foot circumference circle has an area of: 161.1 square feet.
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
divide the circumference (c) by pi (3.14) and then you have diameter. you will have to measure the radius by hand.
The radius of a coin with diameter of 45 mm is : 45/2 = 22.5mm The circumference of a coin with diameter of 45 mm is 45*pi = 141,372mm rounded to 3 decimal places
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
