=> x² = (2.4)² + (4.8)²

=> x² = 5.76 + 23.04

=> x² = 28.8

=> x = 5.366563146

=> x = 5.4

Ans: 2nd option (5.4)

Answer:

The approximate volume is $1,570\ cm^{3}$

Step-by-step explanation:

we know that

The exact volume of the cylinder is

$V=500\pi \ cm^{3}$

To find the approximate volume of the cylinder, substitute the term $\pi$ by the approximate value of $3.14$ and then multiply

$V=500(3.14)=1,570\ cm^{3}$

28% of x = 100.80
.28 × x = 100.80
.28x = 100.80
x = 100.80/.28
x = 360

Scale drawings are used to show an actual image using lesser dimensions.

The width of the actual gym is 72 feet

The scale is given as:

$Scale = 5\ inches : 8\ feet$

Represent the width of the actual gym with w, so, we have the following equivalent ratio

$45\ inches : w = 5\ inches : 8\ feet$

Cancel out the common units

$45: w = 5: 8\ feet$

Express as fraction

$\frac{45}{w} = \frac{5}{8\ feet}$

Cross multiply

$5w = 45 \times 8\ feet$

Divide both sides by 5

$w = 9\times 8\ feet$

$w = 72\ feet$

Hence, the width of the actual gym is 72 feet
