Question

Maria has a swimming pool in her backyard. Calculate the volume of the swimming pool. Round your answer to the nearest whole number. a0 cubic feet

Answer 1

108 feet cubed

Explanation:

i think its 24 because you do l*w*h so 4 times 6 equals 24, times 4.5 and its 108.

Answer 2

Answer : The volume of the swimming pool is,
`142ft^3`

Step-by-step explanation :

In the given figure, there are two figures are included which are cuboid and 2 hemisphere.

As we know that 2 hemisphere combine to form a sphere.

Volume of swimming pool = Volume of cuboid + Volume 2 hemisphere

Volume of swimming pool = Volume of cuboid + Volume sphere

Volume of swimming pool =
`(l* b* h)+((4)/(3)\pi r^3)`

where,

l = length of cuboid = 6 ft

b = breadth of cuboid = 4 ft

h = height of cuboid = 4.5 ft

r = radius of sphere =
`(Diameter)/(2)=(4ft)/(2)=2ft`

Now put all the given values in the above formula, we get:

Volume of swimming pool =
`(l* b* h)+((4)/(3)\pi r^3)`

Volume of swimming pool =
`(6ft* 4ft* 4.5ft)+((4)/(3)* 3.14* (2ft)^3)`

Volume of swimming pool =
`108ft^3+33.49ft^3`

Volume of swimming pool =
`141.49ft^3`

Volume of swimming pool ≈
`142ft^3`

Therefore, the volume of the swimming pool is,
`142ft^3`
