Given the circumference find the radius
WebThe circumference is equal to 2 times 5 times the radius. So it's going to be equal to 2 times pi times the radius, times 3 meters, which is equal to 6 meters times pi or 6 pi meters. 6 pi meters. Now I could multiply this out. Remember pi is just a number. Pi is 3.14159 going on and on and on. WebWe know that the central angle is 10 degrees. So you have 10 degrees over 360 degrees. So we could simplify this by multiplying both sides by 18 pi. And we get that our arc length is equal to-- well, 10/360 is the same thing as 1/36. So it's equal to 1/36 times 18 pi, so it's 18 pi over 36, which is the same thing as pi/2.

WebFeb 8, 2012 · Given the circumference, divide the circumference by pi (3.1416) to give the diameter of the circle, then divide by 2 to find the radius (half of the diameter).Since … WebNov 28, 2024 · Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. \(7\divide 2=3.5\) The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.
WebOn the left-hand side, pi divided by pi cancels out. 49 divided by two is 24.5. So, if the circumference is 49 pi whatever units, then the radius is going to be 24.5 of those units. … WebThe area of a circle is given by the formula. A = pir2. However you can calculate the area from other parameters such as the diameter or the circumference. Since diameter is twice the radius, it is easy to convert the diameter into radius. i.e D = 2r ⇒ r = d2.
