Answer:

4.5 m

Step-by-step explanation:

Distance from center to the the bottom part where headroom begins is 3.9 m-2.6 m=1.3 m

Since the radius is 2.6 m and acts as hypotenuse(see attached image), then the other length will be

$\sqrt {2.6^{2}-1.3^{2}=5.07}=2.25166605
$

Approximately 2.25 m

The half width is 2.25 m hence full width will be 2.25*2=4.5 m

Jesper can run 6 miles in 45 minutes. He is thinking about running in two different races, a 9-mile race and a 15-mile race. At

marin [14]

Find minutes per mile by dividing time by distance:

45 minutes / 6 miles = 7.5 minutes per mile

Now multiply his speed by each distance:

7.5 x 9 = 67.5 minutes

7.5 x 15 = 112.5 minutes

Now subtract the two:

112.5 - 67.5 = 45 minutes more

Help<br> Find the volume of this cone.<br> Use 3 for TT.

natima [27]

Answer:

$180ft^{3}$

Step-by-step explanation:

Volume of a cone:

$V=\pi r^{2} \frac{h}{3}$

Take $\pi$ as 3, as mentioned in the question

'r' is 'radius' ⇒ {diameter is given so divide by 2: 12/2 = 6}

'h' is 'height'

$V=(3)(6)^{2} (\frac{5}{3} )$

$V=(3)(36)(\frac{5}{3} )$

$V=108(\frac{5}{3} )$

{multiply 108 with 5 and then divide the answer by 3}

$V=108$ × $5$

$V=540$

$V=540/3$

$V=180ft^{3}$
