2. The volume of mulch needed is the area of the semicircle multiplied by the depth of the mulch: A = π r2 / 2 A = (3.14)(52 / 2 A = 39.25 ft2 The depth of the mulch is in inches, so we'll multiply the area by (2/12), which is the depth in feet: V = 39.25...
Semicircle area formula Knowing the semicircle definition – half of a circle – we can easily write the semicircle area formula using the well-known circle area, π⋅r2π⋅r2: Asemicircle=Acircle2=π⋅r22Asemicircle=2Acircle=2π⋅r2 The area of a semicircle is just half of the ...
a pizza slice is an example of a sector that represents afractionof a pizza. There are two types of sectors: minor and major sectors. A minor sector is a sector that is less than a semi-circle, whereas, a major sector is a sector greater than a semi-circle. ...

Circumference of a SemicircleThe circumference of a semicircle is equal to half of the circumference of a circle.i.e., the circumference of a semicircle \( = \frac{1}{2}\left( {2\pi r} \right) + 2r = \pi r + d\)How to find Width of Concentric Circles?
Question 3: Explain what is the formula of semi-circle perimeter? Answer: The circle’s circumference formula, C, is C = 2 * pi * r. A semicircle means half a circle. Therefore, in order to find the area of a semi-circle, one would need to divide the perimeter formula by two. Qu...
