Given :

  • Circumference : 136 metres

To find :

  • Radius
  • Area

Solution :

We know that,

  • Circumference = 2πr
  • 2πr = 136 m
  • r = 136m/2 x π
  • r = 21.65m

Hence, our radius would be equal to 21.65m

Also,

we know that,

  • Area = πr²
  • Area = 1472.54m²

Hence ,our area would be equal to 1472.54m².

Answer:

The radius of the circle is 22 meters.

The area of the circle is 1472square meters.

Explanation:

Given that the circumference of the circle is 136 meters, we can find the radius using the formula:


\sf \textsf{Circumference of circle } = 2* \pi * radius

where

  • π is equal to 3.141592654

Substituting value in the above formula:


\sf 136 m = 2 * 3.141592654 * radius


\sf 136 m = 6.283185307 * radius

Dividing both sides by 6.283185307.


\sf (136m)/(6.283185307) = (6.283185307 * radius)/(6.283185307)


\sf radius = 21.64507226


\sf \sf radius\approx 22 \textsf{ m in perfect value}

Therefore, the radius of the circle is 22 meters.

Now,

The area of the circle can be found using the formula:


\sf Area = \pi * radius^2

where

  • π is equal to 3.141592654

Plugging in the radius we found, we get:


\sf Area = 3.141592654 * (21.64507226 )^2


\sf Area = 3.141592654 * 468.5091532


\sf Area = 1471.864914 m^2


\sf Area = 1472 m^2 \textsf{ in perfect value}

Therefore, the area of the circle is 1472 square meters.
