3 of 8<br> The area of a circle is 16.71cm2.<br> Find the length of the radius rounded to 2 DP.

Cerrena [4.2K]

Answer:

Radius = 2.31 cm

Step-by-step explanation:

Area of circle = 16.71 square centimeters

$\pi r^2 = 16.71 \\3.14r^2=16.71\\r^2=\frac{16.71}{3.14}\\r^2=5.32\\\sqrt{r^2}=\sqrt{5.32}\\r=2.306$

Radius of circle = 2.31 centimeter

Solve by quadratic formula. x squared plus x plus 1 = 0

Tasya [4]

Remember that the quadratic formula is: $\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$ .

$a$ stands for the coefficient of the first term, the one associated with the $x^2$ , $b$ stands for the coefficient of the second term, the one associated with $x$ , and $c$ stands for the value of the constant.

In $x^2 + x + 1 = 0$ , our a-value is 1, our b-value is also 1, and our c-value is also 1.

Thus, when we plug in our values into our formula, we get the answer:

$\dfrac{-1 \pm \sqrt{1^2 - 4(1)(1)}}{2(1)} = \dfrac{-1 \pm \sqrt{-3}}{2}$

Simplifying this answer using $i = \sqrt{-1}$ , we get our final answer of:

$\boxed{x = \dfrac{-1 \pm i\sqrt{3}}{2}}$

Create a sample division problem with a 2-digit divisor and give an incorrect answer, showing the steps taken to get the incorre

Makovka662 [10]

Answer:

Incorrect Answer Below

Step-by-step explanation:

Problem: We have a total of 28 candies that need to be divided evenly between 4 students.

(Incorrect) Solution: In order to solve this problem we can seperate the total number of candies into single digits and then divide each digit by 4 like so...

2 / 4 = 0.5

8 / 4 = 2

Now that we have the answer of both of these divisions we can simply add these values together to get the number of candies each student will get

0.5 + 2 = 2.5 candies
