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

put up a picture so people can you

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).
