So 40 (2 radii means one diameter) times pi is 125.6 inches. More specifically, it is a set of all points in a plane that are equidistant from a given point, called the center. What are the units used for the ideal gas law? To find area from the circle's diameter: a = \pi (d/2)^2 a = (d/2)2 Using the Diameter Calculator You can enter the diameter and then compute radius and circumference in mils, inches, feet, yards, miles, millimeters, centimeters, meters and kilometers. Large circular tables for groups of 10-12 people have diameters between 7'-8' (213-244 cm). Radius = D/2 = 14 cm. How do I determine the molecular shape of a molecule? 12. It's simplest to convert circumference to radius first, then find the circle's area: You can enter the circumference and also compute radius and diameter in mils, inches, feet, yards, miles, millimeters, centimeters, meters and kilometers. How do you find the diameter if you have the circumference? = square root. A chord that passes through the center of the circle is a diameter of the circle. So 5x2=10 so your diameter is 10. bye. When can I find the diameter of the circumference of a circle of a circle? Please provide any value below to calculate the remaining values of a circle. Viewed 9k times 3 $\begingroup$ .

Compute the area using these units: square mils, square inches, square feet, square yards, square miles, acres, hectares, square millimeters, square centimeters, square meters, and square kilometers. Area of a circle is r^2 So 20 x 20 (radius squared) times pi is 1256. For example, if the diameter is 16 feet, then the radius is 16 / 2 = 8 feet. Check out 23 similar 2d geometry calculators , How to find circumference from diameter: an example, Circumference and area of a circle calculator. This calculator works both ways, so you can also convert a diameter to a circumference. To calculate circumference (C) from a circles diameter, multiply the diameter by , or C = d. DQYDJ may be compensated by our partners if you make purchases through links. Area = 1256 inches squared. A Diameter is 2x a radius So we need our diameter to be an radius Simply divide 17 to two since diameter is 2x a radius So it will be: A=3.14 times 8.5 inches A=26.690inches Our area is 69.690 inches Thank you :) Pa brainliest po kung maaari #carryonlearning How to get diameter from the circumference. It is twice the radius. In other words, pi equals the circumference divided by the diameter ( = c/d). Most questions answered within 4 hours. Area = 1256 inches squared. 19" Radius Curve. If possible, ask another person to help you with this step. It is an irrational number, so we typically use approximations such as 3.14 or 22/7. for this problem then: C = 3.14159265359 (20) C = 62.83 (rounded to the hundredths place) Not seeing that as an answer listed :-) Hope this helps! Free shipping for many products! To calculate circumference from a circles radius, multiply the radius by 2, and then multiply the result by , or C = 2r. There are three dimensions most often used to describe a circle: Starting from the diameter, you can easily find the other two.
