Find radius of a circle from diameter
WebNov 28, 2024 · The answer is the diameter, d=22 cm. Example 6.8.3. Solve for the radius of a circle if area=153.86 sq. in. Solution. First, write the formula. A = πr2. Next, substitute in what you know. 153.86 = (3.14)r2. Next, begin isolating the r by dividing both sides of the equation by 3.14. WebTo find the circumference of a circle, we can use either of the following formulas: ... To find area with circumference, you divide the circumference by pi, to get your diameter. Then, you find the radius by dividing the diameter by 2. You then multiply your radius by itself and multiply that product by pi. Hope this Helps! :)
