A 45-foot diameter circle has an area of 1,590.4 square feet.
A 45-foot circumference circle has an area of: 161.1 square feet.
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.
Area of circle = Pi x diameter2/4 = 3.142 x 49/4 = 38.49 sq ft
Using 3.14 as Pi the area of circle is: 1589.6250000000002
If radius = 45 mm, then area = 6361.7 mm2 (to 1 dp).

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.
Divide the angle sector by 360 and multiply it by 24 square meters. The area is equal to 3 square meters.
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

There are 360 degrees in a circle so 45 degrees is 1/8th of a circle.
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 area of a circle can be calculated using the formula A = ฯr^2, where r is the radius. Given a radius of 45 km, the area would be approximately 6,366 square kilometers.
