A circle with a radius of 45 units has a circumference of 282.74 units.
Using 3.14 as Pi the area of circle is: 6358.500000000001
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
25%. 45 degrees. Radius.
90mm / 2 = 45 mm
If radius = 45 mm, then area = 6361.7 mm2 (to 1 dp).
A circle with a radius of 45 units has a circumference of 282.74 units.
The area of a circle can be calculated using the formula A = πr^2, where r is the radius. Given a radius of 45 km, the area would be approximately 6,366 square kilometers.
Radius is 45.

Presumably you mean the area of a circle? Area of a circle = pi*radius2 Area = pi*3.82 = 45.36459792 Area = 45 square meters to the nearest square meter.
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
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
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
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
