WebGiven the radius of a circle calculate the area, circumference and diameter. Putting A, C and d in terms of r the equations are: A = π r 2. C = 2 π r. d = 2 r. Calculate r, C and d Given A. Given the area of a circle calculate the …
WebFeb 17, 2016 · A. In order to calculate a circle’s circumference, we need to know either its diameter or its radius. We then use the appropriate value in this equation: C = 2 π r (where “ r ” represents radius, of course). Ex. Find the circumference of this circle: r = 10 units 2 = 5 units. C = 2 π r = 2 π × 5 = 10 π units. Q. candy none bar barWebFeb 20, 2011 · How would you find out the area of a circle if you have only got the diameter? • 2 comments ( 6 votes) Nicholas 5 years ago All you have to do is divide the circumference by 2 to get the radius, then follow the formula of pi * … fish wings and tingsWebMar 29, 2024 · Multiply the radius by . If you are not using a calculator, use the approximation for your calculations. Rewrite the formula using this new value, which represents the circle’s circumference.
