Answer:

About 9.52.

Step-by-step explanation:

The question is asking you to simplify this expression. Since I'm not sure whether or not it wants you to fully solve this or not, I will do both ways.

Just simplifying the expression- 12 squared is about 3.4, and 8 squared is about 2.8. Now the expression is 3.4 x 2.8. Now the equation is simplified.

Simplifying and solving the expression- Now all you have to do if multiply the simplified expression. 3.4 x 2.8 = 9.52

Sorry if this a little off, but I'm not if your teacher wants you to round the decimal a certain way or not. Please let me know if it was right or if you have questions :)

Answer:

Area of the circle = $28.26cm^2$

Step-by-step explanation:

Radius of the circle= 3 cm

Area of the circle= $\pi *r^2$

As,

$\pi =\frac{22}{7}=3.14$

Putting the values in the formula:

Area of the circle= $3.14*3*3$

$=3.14*9\\\\=28.26cm^2$

The area of the circle is $28.26cm^2$

Simplify: −3 • −26 A. −78 B. −68 C. 68 D. 78

hammer [34]

-3 x -26 = 78

meaning the answer is D.

The reason the answer is D, is because two negatives when multiplied or divided become positive. Only when multiplied or divided does this occur.
