<PRE><B>Question 476996</B>
the height of a cylinder is the same length as the circumference of its base. 
its measured height is 125.66 cm calculate the surface area and the volume of the cylinder
:
Find the radius of the cylinder, using the circumference formula
{{{2*pi*r}}} = 125.66
r = {{{125.66/(2*pi)}}}
r = 19.9994 ~ 20 cm is the radius
:
Vol = {{{pi*r^2*h}}}
V = {{{pi*20^2*125.66}}} 
V = 157,909 cu/cm
:
S.A. = Circumference * height + {{{2*pi*r^2}}}; (includes the two ends)
S.A = (125.66 * 125.66) + ({{{2*pi*20^2}}})
S.A = 15790.4 + 2513.3
S.A. = 18,303.7 sq/sm</PRE>
