Rounding a 10-meters long rope to form a circle will give you a circle whose circumference is 10 meters. In every circle, the following formula links radius and circumference together:
So, in your case, the radius will be
which we can best approximate as 1.59
Answer:
r ≅ 3.00
Step-by-step explanation:
First we need to get the formula for finding the volume of sphere. The formula is:
Now to find for the radius, we need to input the value that we know into the formula.
Now we multiply both sides by 3/4.
Now divide both sides by π.
To find r, we finally get the cube root of both sides.
![\sqrt[3]{r^{3} }= \sqrt[3]{27.01}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E%7B3%7D%20%7D%3D%20%5Csqrt%5B3%5D%7B27.01%7D)
r ≅ 3.00
Answer:
The factored form of this is (x - 7)(x -4)
Step-by-step explanation:
In order to factor quadratic equaitons with a 1 as the first coefficient, we look for two numbers that multiply to the last number (28), but add up to the middle number (-11). To do this, we often list the factors of the last number.
Factors of 28
1, 28
-1, -28
2, 14
-2, -14
4, 7
-4, -7
The numbers -4 and -7 satisfy this requirement and are therefore the numbers we want. Now we stick them into parenthesis along with x terms in the front like this:
(x - 7)(x -4)
And that is the fully factored form.

2|5

2-Growth
3-125%

5-Decay
