Question

If diameter of a circle is 14 M. Then find its area, radius, and circumference?

Answer 1

Explanation:

why do you feel this is so complicated ?

you look up the formulas, grab a calculator and then just calculate the results.

please let me know, if you don't understand something :

the diameter is a line from one end of the circle to the other going through the center point of the circle.

therefore, the diameter is 2 times the distance from the center to its arc.

the radius is only one time the distance of the center of the circle to the arc.

so, radius = diameter/2 = 14/2 = 7 M.

the circumference of a circle is

2pi×r = 2×7×pi = 14pi = 43.98229715... M

the area of a circle is

pi×r² = pi×7² = 49pi = 153.93804... M²

Answer 2

Given that the diameter of the circle is 14 meters.

To find the area of the circle, we can use the formula:

Area = π x (radius)^2

where π is a mathematical constant approximately equal to 3.14159.

The radius of the circle is half of the diameter, so we have:

radius = diameter / 2 = 14 / 2 = 7 meters

Now we can find the area of the circle:

Area = π x (radius)^2 = 3.14159 x (7)^2 = 153.938 square meters (rounded to three decimal places).

To find the circumference of the circle, we can use the formula:

Circumference = π x diameter

So, the circumference of the circle is:

Circumference = π x diameter = 3.14159 x 14 = 43.982 meters (rounded to three decimal places).

Therefore, the area of the circle is 153.938 square meters, the radius is 7 meters, and the circumference is 43.982 meters.
