Question

Please, I give 20 score. Find the volume

Answer 1

Answer:

2388.16 in³

Step-by-step explanation:

1) find volume of cylinder

formula: πr²h

given:

π = 3.14

r = 8/2 = 4 in

h = 9 in

$\pi \: r {}^{2} h$

$(3.14) \times (4 {}^{2} ) \times 9$

$3.14 \times 16 \times 9$

$452.16 \: {in}^{3}$

2) find volume of cuboid

formula: length × width × height

given:

length = 16 in

width = 11 in

height = 11 in

$l \: \times w \: \times h$

$16 \times 11 \times 11$

$1936 \: in {}^{3}$

total volume of figure

= volume of cylinder + volume of cuboid

= 452.16 in³ + 1936 in³

= 2388.16 in³
