Find the diameter of a circle if the area is 153.86m2. use 3.14 for pi.

The diameter is 14 m

Step-by-step explanation:

The area of a circle is given by the formula

A = pi r^2

Substituting in what we know

153.86 = 3.14 r^2

Divide each side by 3.14

153.86/3.14 = 3.14/3.14 r^2

49 = r^2

Take the square root of each side

sqrt(49) = sqrt(r^2)

7 =r

We want to find the diameter

d =2*r

d =2*7

d=14

The diameter is 14 m

diameter = 14 m

Step-by-step explanation:

Area of a circle formula:  A = πr^2

Step 1:  Plug in 153.86 for A and use 3.14 for π

A = πr^2

153.86 = (3.14) * r^2

Step 2:  Divide both sides by 3.14

153.86 / 3.14 = ((3.14) * r^2) / 3.14

49 = r^2

Step 3:  Square root both sides

49 = r^2

7 = r

Step 4:  Since we found the radius, multiply it by 2 to get the diameter

diameter = radius * 2

diameter = 7 * 2

diameter = 14

 diameter = 14 m

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes. 

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
