11C3 = 11!/3!(11-3)!

= 11!/(3!x8!)

=(11x10x9x8!)/(3x2x8!)

=11x10x9/6

Find the volume of a cylinder with a radius of 3cm and a height of 7 cm.

svetoff [14.1K]

Answer:

The volume of the cylinder ≅ 197.82 $cm^{2}$

Step-by-step explanation:

The volume of a cylinder is equal to the area of the base times the height. We know the radius, therefore we can find the area of the base. The formula for the volume of the cylinder is as follows:

V = π $r^{2}$ $h$

(now substitute the values of "r" and "h", and get...)

V = π $r^{2}$ $h$

$V = (3^{2} )(7)$ x π

V = (9)(7)π

V = 63π

V ≅ 197.82 $cm^{2}$
