finding volume

Apr 26th, 2015

Diameter of cylinder, d = 12

Radius of cylinder, r = d/2 = 12/2 = 6

Height of cylinder, h = 24


Volume of cylinder

=π * r^2 * h

=π * 6^2 * 24

=π * 36 * 24

= 864π

=864 * 3.14

= 2712.96


ANSWER: Volume = 864π = 2712.96

what is the surface area of a cube with 14 as height and width and length in pi form ?


Apr 26th, 2015

For a cube all sides are equal

Side length, a = 14.

Surface area of cube = 6a^2

Surface area of cube = 6*(14)^2

Surface area of cube = 1176
