What Is The Radius Of A 5 Foot Circle?
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. WebCircumference of a cicle in terms of radius:. Circumference = 2·π·r = 2·3.14·2.5 = 15.7 (*) In terms of diameter:. Circumference = π·d = 3.14·5 = 15.7 (*) In terms of area:. … graphic arts blue book
What is the circumference of a circle with diameter 5 inches?
WebFeb 17, 2024 · The circumference of a circle is \(C=2πr\), where \(r\) is the radius of the circle. We are not given the radius of the circular garden but we can use the given area of the circle to find it. The area of a circle is: \(A=πr^2\) Since the area of our circle is 706.5 square feet, we have: \(706.5=3.14r^2\) Solving for \(r\), we get: WebCircumference of a cicle in terms of radius:. Circumference = 2·π·r = 2·3.14·3.75 = 23.56 (*) In terms of diameter:. Circumference = π·d = 3.14·7.5 = 23.55 (*) In terms of area:.
