Answer V≈351.86

Step-by-step explanation: V=πr2h=π·42·7≈351.85838

The formula for the volume of a cylinder is V=Bh or V=πr2h .

The radius of the cylinder is 4 cm and the height is 7 cm.

Substitute 4 for r and 7 for h in the formula V=πr2h .

V= pie (4)² (7)

v= pie ( 14) (49)

A glider flies 13 miles north from the airport and then 24 miles diagonally southeast. Approximately how far west does the glide

NISA [10]

Answer:

20.2 miles

Step-by-step explanation:

This can be described by the three sides of a right angled triangle. Let the distance of the glider to the airport be represented by x, applying the Pythagoras theorem:

$/hyp/^{2}$ = $/adj1/^{2}$ + $/adj2/^{2}$

$/24/^{2}$ = $/x/^{2}$ + $/13/^{2}$

576 = $x^{2}$ + 169

$x^{2}$ = 576 - 169

= 407

x = $\sqrt{407}$

= 20.1742

x = 20.2 miles

The glider has to fly 20.2 miles to return to the airport.

Answer:

The answer is "50%".

Step-by-step explanation:

Please find the complete question in the attached file.

In the given question when we deduct the 'yes' from the 'yes' on the L graph also on the given R graph, it might be presumed that about $\frac{1}{2}$ of its circle on the L still exists, which is equal to $\frac{1}{2}$ or 50%.
