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

Answer:

108 feet cubed

Step-by-step 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 = $(l\times b\times h)+(\frac{4}{3}\pi r^3)$

where,

l = length of cuboid = 6 ft

b = breadth of cuboid = 4 ft

h = height of cuboid = 4.5 ft

r = radius of sphere = $\frac{Diameter}{2}=\frac{4ft}{2}=2ft$

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

Volume of swimming pool = $(l\times b\times h)+(\frac{4}{3}\pi r^3)$

Volume of swimming pool = $(6ft\times 4ft\times 4.5ft)+(\frac{4}{3}\times 3.14\times (2ft)^3)$

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, $142ft^3$
