Jake has finished pouring 4,865 cubic feet out of a total of 27,000 cubic feet of concrete. What percent of the job has he compl

anzhelika [568]

The total is the 100% and that is 27000, the question is what percentage is 4865
We can use a simple rule of three, direct proportion to solve:
27000 ft^3 --------> 100%
4865 ft^3 ---------> x
x =(4865)(100)/27000
x = 18.02
therefore 4865 ft^3 is 18.02% of 27000 <span>ft^3</span>

Can someone help please?

Answer:

Part 1) The area of the structure is $2,453.25\ ft^{2}$

Part 2) The slab will contain $1,226.625\ ft^{3}$ of cement

Step-by-step explanation:

Part 1) Find the area of the structure

we know that

The area of the structure is equal to the area of rectangle plus the area of semicircle

<u><em>Find the area of rectangle</em></u>

The area of rectangle is equal to

$A=LW$

we have

$L=70\ ft$

$W=30\ ft$

substitute

$A=(70)(30)$

$A=2,100\ ft^{2}$

<u><em>Find the area of semicircle</em></u>

The area of semicircle is

$A=\frac{1}{2}\pi r^{2}$

we have

$\pi =3.14$

$r=15\ ft$

substitute

$A=\frac{1}{2}(3.14)(15)^{2}$

$A=353.25\ ft^{2}$

<u><em>Find the area of the structure</em></u>

Adds the areas

$A=2,100+353.25=2,453.25\ ft^{2}$

Part 2) If the structure is 6 in thick, how many cubic feet of cement will the slab contain?

Remember that

$1\ foot=12\ inches$

Convert inches to feet

$6\ in=6/12=0.5\ ft$

<u><em>Find the volume of the structure</em></u>

To obtain the volume , multiply the area by 0.5 ft (thick)

so

$V=2,453.25*0.5=1,226.625\ ft^{3}$
