Question

The perimeter of a semi circle is 288 then find the radius

Answer 1

The radius of the semicircle would be 56 units.

Given :
Perimeter = 288
To find: Radius
Solution:
The perimeter of a semicircle is the total time of allure line. It is smooth to reckon the border of shapes that have straight edges, like in the case of a square, place all the hands maybe absolutely additional. However, the border of a hemicycle has a various rule because a arc is the half of a circle, and it resides of a bowed and a straight frontier.

Let take the formula of perimeter of a semicircle,
$\pi r + 2r$
$\pi r + 2r$ = 288
$r(\pi +2)$ $= 288$
r = 288/5.173
r = 55.95
By rounding off we get r = 56

Hence the radius of the semicircle would be 56 units.
