Answer:

should be 12.56

Step-by-step explanation:

the formula to find the area of a circle is A= πr2

so what you do is mulitply 3.14 ( number of pi) times radius (half of what the diameter is) squared which is the radius times the radius

3.14 x 2 x 2 + 12.56

How would you describe a meter in English units?

dalvyx [7]

The answer is letter A. A meter has nearly the same value to a yard, one yard approximately amounting to 1.09361 meter. The rest of the other measures are far from meter's value in distance.

Is the answer a, b, c, or d.

ale4655 [162]

The correct answer is d.

We have the following system of linear equations:

(I) $4x+7y=-14$
(II) $8x+5y=8$

Let's use the elimination method, then let's multiply the equation (1) $\times(-2)$ and subtracting (I) and (II):

(I) $-2(4x+7y)=-2(-14)$
∴ $-8x-14y=28$

(I) $-8x-14y=28$
(II) $8x+5y=8$
____________________
(III) $-9y=36$

∴ $y=-4$

We can find the value of x by substituting y either in (I) or (II). Thus, from (I):

$4x+7(-4)=-14$
∴ $4x-28=-14$
∴ $4x=14$
∴ $x=\frac{14}{4}$
∴ $\boxed{x=\frac{7}{2}}$

Let's substitute the values of x and y into (I) and (2)

(I) $4(\frac{7}{2})+7(-4)=14-28=-14$
(II) $8(\frac{7}{2})+5(-4)=28-20=8$

Finally the answer is:

$\boxed{x=\frac{7}{2} \rightarrow x= 3 \frac{1}{2}}$
