Firstof all, converting measurements from inches to centimeters as follows: 20in to cm = 20 * 2.54 = 50.8 cm. Now we have: Scale Length = (d1/d2) * Real Length. Scale Length = (1/10) * 50.8 cm. Scale Length = 5.08 cm. How Scale Calculator Works? This free scale finder exactly finds the real and scaled size values of the figures as per theTheoriginal shape is 3 by 4 so we multiply those to find the area of 12 square units. The new shape has length of 3x2 (3 x the scale factor) and height of 4x2 (4 x the scale factor). The dimensions of our scale drawing are 6 by 8 which gives us an area of 48 square units. Notice when we found the new dimensions we multiplied the 3 and 4 EACH
Whatis the area of a circle with a DIAMETER of 100 cm (radius of 50 cm)? How big is a 100 centimeter circle? Use this easy and mobile-friendly calculator to compute the area of a circle given its diameter.
Acircle of radius = 1.25 or diameter = 2.5 or area = 4.909 inches has a circumference of 7.854 inches which is equal to: Use the this circumference length calculator above to find the perimeter of a circle given its diameter, or other parameters.
Inorder to find the actual dimensions from a floor plan, you can set up and solve a proportion. The scale given in the drawing is the first ratio. The diameter of the fountain is 4 centimeters. What is the actual diameter of the fountain? First, set up a proportion. The scale for the image says that 1 c m = 0.5 m, therefore the proportion is: x25Lej.4 cm circle actual size
