A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?
Elodia [21]

Answer:

28 ft²

Step-by-step explanation:

The area of a circle is \pi r^2, where r = radius. To find the radius, we split the diameter in half.

  • 6/2 = 3
  • Thus, the radius is 3.

Now, let's find the area of the circle and approximate pi to 3.14.

  • 3.14*3^2
  • 3.14*9
  • 28.26
  • 28.26 ≈ 28 ft²

Therefore, the answer is 28 ft².

A rectangle has a perimeter of 204 feet. It's length is six feet longer than twice it's width. If L stands for the length of the
Ratling [72]

Answer:

L = 70

W = 32

Step-by-step explanation:

P = 2L + 2W

P 204 feet

W = x

L  = 2x + 6

P = 2L + 2W

P = 2*(2x + 6) + 2*x

P = 4x + 12 + 2x

P = 6x + 12

But we know that P = 204  So 6x + 12 = 204

6x + 12 = 204                    Subtract 12 from both sides

6x + 12 - 12 = 204 - 12       Collect like terms on the right

6x = 192                             Divide by 6

x = 192/6

x = 32

Answer

W = 32

L = 2*W + 6

L = 2*32 + 6

L = 64 + 6

L = 70
