A volcano on a recently discovered planet rises to a height of .
Use the table of facts to find the height of 15.338 mi. the volcano in feet.
Round your answer to the nearest tenth.

12 inches ( in ) = 1 foot ( ft )
3 feet ( ft ) = 1 yard ( yd )
36 inches ( in ) = 1 yard ( yd )
5280 feet ( ft ) = 1 mile ( mi )
1760 yards ( yd ) = 1 mile ( mi )

Answers

Answer:

21 km

Step-by-step explanation:

The volcano has a height of over 21 km (13.6 mi or 72,000 ft) as measured by the Mars Orbiter Laser Altimeter (MOLA). Olympus Mons is about two and a half times Mount Everest's height above sea level.

Unit conversion is the conversion of one unit to another unit with its standard conversion.

The height of the volcano is 15.338 miles.

1 mile = 5280 feet.

15.338 miles = 80984.6 feet.

The height of the volcano in feet is 80984.6 feet.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 meter = 100 cm

We have,

The height of the volcano = 15.338 miles ___(1)

It is given that,

1 mile = 5280 feet _____(2)

From (1) and (2) we get,

15.338 miles

= 15.338 x 1 mile

= 15.338 x 5280 feet

= 80984.64 feet

Rounding to the nearest tenth.

= 80984.6 feet

Thus,

The height of the volcano is 15.338 miles.

1 mile = 5280 feet.

15.338 miles = 80984.6 feet.

The height of the volcano in feet is 80984.6 feet.
