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.

Solve for x in the equation x^2+10x+12=36.

Alexandra [31]

Solve for x:
x^2 + 10 x + 12 = 36

36 = 36:
x^2 + 10 x + 12 = 36

Subtract 12 from both sides:
x^2 + 10 x = 24

Add 25 to both sides:
x^2 + 10 x + 25 = 49

Write the left hand side as a square:
(x + 5)^2 = 49

Take the square root of both sides:
x + 5 = 7 or x + 5 = -7

Subtract 5 from both sides:
x = 2 or x + 5 = -7

Subtract 5 from both sides:
Answer: x = 2 or x = -12 Thus the Answer is A.
