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.

il63 [147K]

Answer:

Step-by-step explanation:

so your equation would look like $\frac{69+x}{2}=41$

Next multiply both sides by to clear the fraction $2*(\frac{69+x}{2})$

to get $69+x=89$

Subtract 69 from both sides $69+x=82\\-69 -69$

you get $x = 13$
