What is the area if the radius is 3.8 meters?
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.
What is the area of 45mm diameter circle?
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
What is the area of a circle with the circumference 6.28?
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
What is the area of a sector if the central angle is 45 degrees?
An eighth of the area of the circle which, since neither its radius, diameter nor circumference are known, is an unknown quantity.
What is the area of a circle with a diameter of 70 mm?
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
Quarter of a circle?
25%. 45 degrees. Radius.
What is the radius of a circle whose diameter is 64cm?
32cm, the radius is half of the diameter
