Answer:

$38.47 {m}^{2}$

Step-by-step explanation:

The formula to find the area of a circle is

$a= \pi {r}^{2}$

We know that

$\pi = 3.14 \: \: \: \: \: \: r = 3.5$

Therefore the area is

$a= \pi {r}^{2} \\ \\ a = (3.14) {(3.5)}^{2} \\ \\ a = 3.14 \times 12.25 \\ \\ a = 38.47 {m}^{2}$

Here is a thorough explanation.

Interval notation is a way of writing subsets of the real number line . A closed interval is one that includes its endpoints: for example, the set {x | −3≤x≤1} . To write this interval in interval notation, we use closed brackets [ ]: [−3,1]

Answer:

200 feet

Step-by-step explanation:

Area of the warehouse $=60,000$ ft^2$

Let the length of the warehouse=l

The warehouse's width is exactly $\dfrac23$ of its length

Therefore: Width of the warehouse $=\dfrac23l$

Area =Length X Width

Therefore:

$\dfrac23l*l=60000\\$Cross multiply\\2l^2=60000*3\\2l^2=180000\\$Divide both sides by 2\\2l^2 \div 2=180000 \div 2\\l^2=90000\\l^2=300^2\\$Length, l=300 feet\\Recall: Width =\dfrac23l\\$Therefore, Width of the warehouse=\dfrac23*300=200$ feet$
