Question

Please, I give 20 score. Find the volume

Answer 1

2388.16 in³

Explanation:

1) find volume of cylinder

formula: πr²h

given:

π = 3.14

r = 8/2 = 4 in

h = 9 in

`\pi \: r {}^(2) h`

`(3.14) * (4 {}^(2) ) * 9`

`3.14 * 16 * 9`

`452.16 \: {in}^(3)`

2) find volume of cuboid

formula: length × width × height

given:

length = 16 in

width = 11 in

height = 11 in

`l \: * w \: * h`

`16 * 11 * 11`

`1936 \: in {}^(3)`

total volume of figure

= volume of cylinder + volume of cuboid

= 452.16 in³ + 1936 in³

= 2388.16 in³
