Answer:4^2≈50.26548

Step-by-step explanation:

   πr2.

   Where r is the radius and π≈3.14 , the ratio of a circle's circumference to    its diameter.

   Plugging in 4 from the radius, we get.

   42π

   ⇒16π inches.

   This is our exact answer. Alternatively, we can plug in 3.14 for π to get.

   50.26 inches.

Julie is digging a square area in her backyard a for a vegtable garden. If the area is 52 square feet, what is the approximate l
AURORKA [14]

Answer:

<em>The correct option will be:   (b) 7 feet.</em>

Step-by-step explanation:

Suppose, the length of the garden is  x feet.

As the <u>shape of the garden is like a square, then the area of the garden</u> will be: (length)^2 = x^2 feet²

Given that, the <u>area is 52 square feet</u>. So, the equation will be.......

x^2= 52\\ \\ x=\sqrt{52} = 7.211.... \approx 7

So, the approximate length of the garden will be 7 feet.

HELP!!!! I cannot find any good answers for this question and I keep getting it wrong! The answer options are:
kondaur [170]

The missing reason is (d) Add the fractions together on the right side of the equation

<h3>How to complete the missing reason?</h3>

From the statements, we have the following equation:

x^2 + b/a x + (b/2a)^2 = -4ac/4a^2 + b^2/4a^2

Next, we add the fractions on the right-hand side of the equation.

This gives

x^2 + b/a x + (b/2a)^2 = [-4ac + b^2]/4a^2

The above means that the last statement is gotten by adding the fractions on the right-hand side of the equation.

Hence, the missing reason is (d) Add the fractions together on the right side of the equation

SCORPION-xisa [38]
Width: x
Length: 2x
Perimeter=2x+2x+x+x=6x
32 cm more than width means x+32
6x=x+32
5x=32
x=6.4
Dimension is 6.4×12.8 (width×length)
