Aferris wheel has a diameter of 42 feet. it rotates 3 times per minute. approximately how far will a passenger travel during a 5-minute ride?
132 feet
659 feet
1,978 feet
3,956 feet

Step-by-step explanation:

Step 1

Find the circumference of the Ferris wheel

we know that

The circumference of a circle (Ferris wheel) is equal to

we have

substitute

Step 2

The Ferris wheel rotates times per minute

so

In minute travel  

therefore

by proportion

Find how far will a passenger travel during a minute ride

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
