Find Volume And Surface Area.

11^2 = 121

121 x 3.14 = 379.94

Now we multiply by the height:

379.94 x 7.5 = 2,849.55 cm3 is your volume.

Surface Area:

379.94 + 379.94 = 759.88

Now we find circumference:

2 x 3.14 x 11 = 69.08,

69.08 x 7.5 = 518.1

Now we add the given areas:

759.88 + 518.1 = 1,277.98 cm2 is your surface area

14 x 14 = 196

196 x 24 = 4704

4704 divided by 3( x 1/3 ) = 1,568 in3 is your volume.

14 x 14 = 196

14 x 25 x 1/2(basically just dividing by 2) = 175

175 x 4(4 sides of triangles) = 700

Add all the given areas:

196 + 700 = 896 in2 is your surface area.
