You mean what Is the circumference of a circle? pi*(r)squared.
The relevant equation is 2*pi*r*(r+h) = 160.Solve this for h.
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.
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).
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
This is the equation of a semi-circle, or a half circle.
Area= Pi r squared
LOVE
TT in this case is standing in for the greek letter pi (π) TTr2 means "Pi times the radius squared" and is the equation for calculating the area of a circle.

Pi is the ratio of the outside circumference of a circle (perfect) to the radius expressed in the equation Pie are Squared ;) (Pi X R2) Pi is the value of Pi and R is the Radius of the circle.
That's the formula for the area of a circle.

Pi r squared is the formula for the area of a circle. 2 pi r squared is twice that.
SA=2(pi times r squared) + h(pi 2 r) or (easier way) 2 pi r squared + 2 pi r h
pi times the radius squared pi r squared
