45mm * 45mm * 3.14 = 6358.5 sq. mm
219.91mm
Diameter of circle: 70/pi = 22.28 mm rounded to two decimal places
3,848.45mm2.
560mm (70 x 8 = 560).
I don't understand why there are so many questions about rectangles' perimeter. You just add the length and the width and double your answer....
219.91mm
Well if your telling me a line that is perfectly straight through the circle and intersects the center is 70mm long that would be the diameter.

70mm = 7cm
70mm is 2.75591"
The 10x means it magnifies ten times The 70mm means the final lenses (that point to the image) are 70mm in diameter. The larger the diameter, the more light that can enter the binoculars and so the easier it is to see the image. So binoculars 10x50mm and 10x70mm both magnify ten times, but the 70mm diameter lenses allow more light in and so should give a better image. So the larger the second number, the better the image [should be] for a given magnification; however, the larger the second number the larger (and heavier) binoculars become.
70mm is the size of the print. The film is 70mm wide.
The Head unit is about the size of a Egg Cup, 50mm Diameter and 70mm long overall! Good size for the output.
Volume of the cylinder = Area of the Base X Length Area of the Base = Area of a Circle = Pi X r2 where Pi = 3.1416 r = radius of the pipe = 70mm = 0.07mtr Therefore Volume of the Cylinder = 3.1416 x 0.0702 mtr x 1mtr = 0.01539m3
there are 10mm in 1cm so to convert mm to cm you divide by 10. 70mm is therefore 7cm.
