Question

Please answer all three.​

Answer 1

1181.16

Explanation:

Cylinder + Cube = 1181.16

Answer 2

842.04 cm³

Explanation:

Cylinder:

diameter = 6 cm

r = 6/2 = 3cm

h = 4 cm

Volume of cylinder = πr²h

= 3.14 * 3 * 3 * 4

= 113.04 cm³

Cube:

side = 9 cm

Volume of cube = side * side *side

= 9*9*9

= 729 cm³

Volume 0f composite figure = volume of cylinder + volume of cube

= 113.04 + 729

= 842.04 cm³
