Question

Pls help. The question is on the picture

Answer 1

V = 23518 m3

Explanation:

The volume of the cube part of building

(20)(20)(37)=14800 cm3

Each cylinder:

h=37/12=3.083 m

r=10 m

`v=\pi (10)^(2) (3.083)=968.66m^(3)`

all the cylinders:

`v=(12)(968.66)=11,623.89cm^(3)`

Total volume.

`V=14800+(3)/(4) (11,623.89)`

`V=14800+8717.92=23,517.92`

nearest m3:

`V=23518m^(3)`

I hope this help you

Answer 2

23518

Explanation:

1) the total volume can be calculated as the sum of two volumes (for more info see the picture): V=V₁+V₂, where V₁ belongs to the prisma and V₂ - to the cylinder;

2) V₁=a*b*h; V₁=20*20*37=14800 (m³);

V₂=3/4*(π*r²*h); V₂=3/4*3.1415*100*37≈8717,6625 (m³), note the full volume of the cylinder cannot be included into the result, but 3/4 of its volume;

3) finally, V=14800+8717.6625=23517,6625≈23518 (m³).
