Question

wat is the formula to claculate perimeter of semi circle and rectangle as a whole

Answer 1

$\large\underline\mathfrak\red{Answer \: :- }$

Information about perimeter of semi circle :)

• In mathematics (and more specifically geometry), a semicircle is a one-dimensional locus of points that forms half of a circle. The full arc of a semicircle always measures 180° (equivalently, π radians, or a half-turn). It has only one line of symmetry (reflection symmetry).

$\large\underline\mathfrak\green{Formula \: :- }$

$\large\boxed{\bf Perimeter \: of \: semi \: circle = r(π+2) }$

Information about Perimeter of rectangle :)

• The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle.

$\large\underline\mathfrak\green{Formula \: :- }$

$\large\boxed{\bf Perimeter \: of \: rectangle = 2(l+w) }$
