WebThis circumference to diameter calculator is used to find the diameter of a circle given its circumference. Just enter the value of the circumference. Then tap or click the Calculate button. Get the result. You can also select units of measure for both input data and results. WebThe formula for the area of a circle is πr 2. For this particular circle, the area is 81π, so 81π = πr 2. Divide both sides by π and we are left with r 2 =81. Take the square root of both sides to find r=9. The formula for the circumference of the circle is 2πr = 2π(9) = 18π. The correct answer is 18π.
WebArea of a circle: A = π r 2 = π d 2 /4 Circumference of a circle: C = 2 π r = π d. Circle Calculations: Using the formulas above and additional formulas you can calculate properties of a given circle for any given variable. … WebThe circumference is pi times the diameter if it were opened up and straightened out to a line segment. The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.
