2/3 + 3/4 + 4/2. If a fraction appears in your answer, it should be in simplified form.

1 answer:

5 0

We must first make each fraction have a common denominator, this will be 12
2/3 * 4/4 = 8/12
3/4 * 3/3 = 9/12
4/2 * 6/6 = 24/12
we can then add the numerators of each fraction
8 + 9 + 24 = 41
so our answer is 41/12
we can not simplify any further and thus get
41/12

What is the exact circumference of the circle?

cestrela7 [59]

Hello!

What is the exact circumference of the circle?

10π feet

20π feet

40π feet

60π feet

Solving: Using the data (Circle with center A and diameter of 20 feet labeled).

diameter = 2*radius

$20 = 2*r$

$2\:r = 20$

$r = \dfrac{20}{2}$

$\boxed{r = 10\:ft}$

Formula: (Circle length)

$\boxed{C = 2* \pi *r}$

Now, replace in the circumference length formula:

$C = 2\:\pi *r$

$C = 2\:\pi *10$

$\boxed{\boxed{C = 20\:\pi\:ft}}\end{array}}\qquad\quad\checkmark$

Answer:

B. 20π feet

$\underline{The\:exact\:circumference\:of\:the\:circle\:is\:\:20\:\pi\:ft}$
