What does the circumference of a circle?
You mean what Is the circumference of a circle? pi*(r)squared.
How do i find the height of a right cylinder the a surface area of 160 pi squared and a radius of 5?
The relevant equation is 2*pi*r*(r+h) = 160.Solve this for h.
What is the relationship between the area of a circle and its radius squared?
The area of a circle is defined by the equation A = πr^2 where π = pi (3.14...) A = Area r^2 = radius squared So, the radius of a circle squared multiplied by pi equals the area.
Is c equals 2πr the same as c equals πr squared?
No. C = 2*pi*r is the equation representing the circumference of a circle. The area of a circle is equal to pi*(r^2).
What is the circumference of an area if the diameter is 6?
If you mean a circle, the circumference is diameter times pi. Pi is approximately 3.14. The area is pi times the radius squared. The radius can be found using the equation: A = pi(r2), so 6 = 3.14(r2) r = about 1.3824 The diameter can be found using the equation: r = 2d, so d = about 2.7647 The circumference can be found using the equation: C = pi(d), so C = 3.14(2.7647), so C is about 8.68
