Answer: 112 meters

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

  • Volume of a cylinder (V) : π x radius ² x height

Replacing with the values given :

842,411 = π x r ² x 85

Solving for r:

842,411 / (π x 85) = r²

3,154.67 = r²

√3,154.67 = r

56.16 m = r

Finally, we have to multiply the radius by 2 to obtain the diameter:

56.16 x 2 = 112 meters

A= l*w
168= 14*w

Divide both sides by 14
168/14= 14w/14
12=w

Final answer: 12 ft (I'm not sure if you meant to switch the order of b and c).

A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions o
Talja [164]

Percent change is 100%

Step-by-step explanation:

  • Step 1: Find the perimeter of the first garden when length = 6 ft and width = 4 ft

Perimeter = 2 (length + width)

                = 2 (6 + 4) = 2 × 10 = 20 ft

  • Step 2: Find the perimeter of the second garden when length = 12 ft and width = 8 ft (∵ dimensions are doubled)

Perimeter = 2 (12 + 8) = 2 × 20 = 40 ft

  • Step 3: Find the percent change in perimeter

Percent Change = Final value - initial value/Initial Value × 100

                            = (40 - 20/20) × 100

                            = 1 × 100 = 100%

Llana [10]

Roberto paints 1/6 of a room in 1 hour.
Julio paints1/8 of a room in 1 hour.

Working together, they paint (1/6 + 1/8) = (4/24 + 3/24) = 7/24 room per hour.

The reciprocal unit rate is  24/7 hour per room = <em>3-3/7 hours</em> per room.
