What us the difference in the ares of a circle with diameter 4 m and a circle with diameter 6 m? Round your answer to the neares
enyata [817]
Let's calculate each area.
4 m:
We need to divide it by 2 to find the radius.
4÷2=2
Now let's put it in the formula.
2²π
4π=12.5663706≈13
6 m:
We need to divide it by 2 for the radius.
6÷2=3
Now put it in the formula.
3²π
9π=28.2743≈28
Now subtract 13 from 28.
28-13=15
So, the difference between their area is 15 m².

Together,two boxes of spices weigh 4 pounds 8 ounces. Each pound is worth $400. How much are the boxes worth in all.
Zanzabum

The total worth of the 4 pounds and 8 ounces of box is $1800

<h3>Total cost</h3>

Weight of the boxes:

  • 4 pounds
  • 8 ounces
  • Cost of each pound = $400

Convert ounces to pounds:

8 ounces to pounds = 0.5 pounds

Total cost of the boxes = 4 pounds (400) + 0.5 pounds (400)

= 1600 + 200

= $1,800

MATH HELP 10 PTS
Lesechka [4]

Answer:

The width is 5 and the length is 11

Step-by-step explanation:

The formula for perimeter is

P = 2(l+w)

We know the perimeter is 32

32 = 2 (l+w)

Divide each side by 2

32/2 = 2(l+w)

16 = l+w

We know the length is 6 longer than the width

l = w+6

16 = w+6+w

Combine like terms

16 = 2w+6

Subtract 6 from each side

16-6 = 2w+6-6

10 = 2w

Divide by 2

10/2 = 2w/2

5 =w

The length  is

l = w+6

   5+6 = 11
