The surface area is Hx2xRxPI+2xPIxR^2.
So 9x2x4xPI+2xPIx4^2
= 54xPI+32PI = 86PI cm^2
980.1769079
376.86 Units.
Vol = pi*r2*h = 2124 cubic units.
Vol = pi*r2*h = 22619 cubic units.
Take 550mm divide it by 2 to get the radius. Square the value of the radius. Muiltiply that value with 960 and 3.14. You now have your volume of the cylinder in mm. To convert from mm to cm. Divide the value you got by 10. Volume of any cylinder = (Pi) x (radius)^2 x (height).
If it has height it's not a circle, its a cylinder. PS whats a fit?
706.5 cm
A circle with a radius of 5 units has a circumference of 31.42 units.
five whats, inches?
