Frequently Asked Questions

How do you calculate the area of a semi circle?

Area of a Semi-Circle Formula: A = (1/2) * π * r 2. Where, A = Area of Semicircle r = Radius. Just enter the value of radius in the area of a semicircle calculator to compute the semicircle area within a blink of an eye. Area of a Semi-Circle: A semi-circle is half of a circle.

What is the formula for area of a semi circle?

What Do You Mean By the Area of a Semicircle?

  • The area of a half circle generally refers to the space inside the semicircle or the area or region enclosed by it.
  • Here, the area of a semicircle is half the area of a circle.
  • The area of a semicircle or the area of half circle is π R 2 2 .

What is the equation for a semicircle?

The perimeter of a semicircle is the sum of the half of the circumference of the circle and diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius. Therefore, The perimeter of Semicircle = (1/2) π d + d Or Circumference = (πr + 2r) Semi Circle Shape

What is the formula for the radius of a semicircle?

It depends on what characteristics of the semicircle you are given. If you are given the length of the semicircle, then C = 2 (pi)r, the semicircle length therefore is (pi)r, and the radius is the semicircle length divided by pi.
