Answer:

Let's first try to find the radius before finding the diameter because when you find the radius, you double it to get the diameter.

To find the radius, use the area for a circle formula and plug in the values you know so far, so the formula is;

A = πr^{2}

What we know:

  • <u><em>1,017 is the area.</em></u>

Plug that area in our equation:-

A = πr^{2}

1,017 = 3.14r^{2}

Solve for r;

÷3.14  ÷3.14

324(approximate) = r^{2}

√324 = r

18 = r, the <u>radius</u> is around <u>18 square meters</u> (do not mistake the unit for some other unit).

<h2>Therefore, your answer is <u>C</u>.</h2><h3>Another alternative way;</h3>

<u>Plug in your </u><u>options</u><u>' </u><u>numbers</u><u> into the equation;</u>

A = πr^{2}

And by looking at the options, we can see the only number here being used is 18, so we use 18 in the formula for the area of a circle to check if it'll result in 1,017 as the area.

Also: Notice if it says <u>diameter</u> or <u>radius</u> when using this solution, you are looking for the radius first.

Answer:

The answer is C

Step-by-step explanation:

The formula of a circle is pie radius ^2. Its asking for the surface area. So I got C because you do pie 18^2 and gets you approximately 1017. Although A also says 18 as the radius, it says meters. After you solve a surface area problem you do square meters or square units. For volume you have to use   units cubed or units ^3. Make sure to always do this or your teacher might count you as wrong.

Is (0,3) a solution to the equation y=x+3?
Delvig [45]
If you would like to know if (0, 3) is a solution to the equation y = x + 3, you can find this using the following step:

(0, 3) = (x, y)
x = 0
y = 3

y = x + 3
3 = 0 + 3
3 = 3

Result: (0, 3) is a solution to the equation y = x + 3.

Divide 28x3 + 42x2 - 35x by 7x
Fiesta28 [93]
The answer is 4 x^{2} +6x-5

\frac{28 x^{3} +42 x^{2} -35x}{7x} =  \frac{28 x^{3} }{7x} + \frac{42 x^{2} }{7x} - \frac{35x}{7x} =4 x^{2} +6x-5
