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 : The volume of the swimming pool is,

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 =

where,

l = length of cuboid = 6 ft

b = breadth of cuboid = 4 ft

h = height of cuboid = 4.5 ft

r = radius of sphere =

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

Volume of swimming pool =

Volume of swimming pool =

Volume of swimming pool =

Volume of swimming pool =

Volume of swimming pool ≈

Therefore, the volume of the swimming pool is,

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
