Toconvert inches of fabric to centimeters of fabric: There is 2.54 cm in one inch. To convert length in inches to length in centimeters, multiply the number of inches by 2.54 (because in every inch, we've got 2.54 cm). Theangular diameter, angular size, apparent diameter, or apparent size is an angular distance describing how large a sphere or circle appears from a given point of view. In the vision sciences, it is called the visual angle, and in optics, it is the angular aperture (of a lens).The angular diameter can alternatively be thought of as the angular displacement Tocalculate the radius of a circle, divide its circumference by 2π; for the circle's diameter, divide the circumference by π. Let's say that the circumference of a given circle is 20 inches. Therefore, its radius is 3.18 in, and its diameter is 6.37 in. Calculate the diameter of a circle with this tool. Size 32 KB. circle templates are quite easy to use. All you have to do is follow these steps: Choose the size, and number of circles that you want from all the circle templates that we’ve got in our collection. Download them for free and print them out. Colour them the way you want and stick them wherever you want to. Asstudents work, monitor for those who express the scale of the drawing in different but equivalent ways (e.g., 3 cm to 15 m, 1 cm to 5 m, 1 to 500). Also monitor the different ways students find the area of the large rectangular pool: By first finding the actual side lengths of the pool in meters and then multiplying them be12 degrees divided by 8 centimeters, or 9 degrees divided by 6 cm., or 1.5 degrees per cm. If the moon in this image was 1/2 cm (5mm) in diameter, its angular size would be .5 cm. x 1.5 degrees per cm. = .75 degrees. My image is from the (circle one): Finder (12°x9°) Main Zoomed Out (.9°x.7°) Main Zoomed In (.45°x.35°) DiameterCircle Area by Diameter results may be rounded What is the area of a circle with a DIAMETER of 1 cm (radius of 0.5 cm)? How big is a 1 centimeter Acircle of radius = 25 or diameter = 50 or circumference = 157.1 mm has an area of: 1.963 × 10-9 square kilometers (km²) 0.001963 square meters (m²) 19.63 square centimeters (cm²) 1963 square millimeters (mm²) 7.57919 × 10-10 square miles (mi²) 0.00234773 square yards (yd²) 0.0211296 square feet (ft²) 3.04266 square inches (in²) First set up a proportion. The scale in the drawing says that 1′′ = 20′, therefore the proportion is: 1 inch 20 feet. Next, write the second ratio. You know the scale length is 7′′ inches. The unknown length is x. 1 inch 20 feet = 7 inches x feet Then, cross-multiply to solve for x. 1 20 = 7 x 1x = 20 × 7 x = 140. The answer is 140. ND3YIov.
