Answer:

Step-by-step explanation:

-6n + 2.9 = 11

subtract 2.9 from both sides

-6n = 8.1

divide both sides by -6

n = -1.35

2/3n - 3 = 8

add 3 to both sides

2/3n = 11

multiply both sides by 3

2n = 33

divide both sides by 2

n = 16.5

hope this helps <3

Answer:

left side:

-6n = 11 - 2.9

-6n = 8.1

n = - 8.1/6

n = - 1.35

right side:

2/3 n = 8 + 3

2/3 n = 11

n = 33/2

n = 16.5

The area of a circle is 100π ft². What is the circumference, in feet? express your answer in terms of \piπ
Bond [772]

Answer:

20π ft

Step-by-step explanation:

To find the circumference of the circle given its area, first find its radius.

\textcolor{steelblue}{\boxed{\text{Area of circle =}\pi  {r}^{2} }}

Substitute given area into the formula:

100π= πr²

Divide both sides by π:

100= r²

Square root both sides:

r =  \sqrt{100}

r= 10 ft

\textcolor{steelblue}{\boxed{\text{Circumference of circle = }2\pi  {r}}}

Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.

Circumference of circle

= 2(π)(10)

= 20π ft
