How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
What is the approximate area of a semicircle with a diameter of 22 inches?
A semicircle is half a circle, so its area is half that of a circle: radius = 1/2 diameter = 22 ÷ 2 = 11 area = 1/2πr2 = 1/2π112 ~= 190 sq in
How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
What is the width of a semicircle with an area of 180ft squared?
The diameter of the circle is 21.4 feet, approx.
Which solid is formed when a semicircle is revolved about a line containing the diameter of the semicircle?
a sphere

What is the diameter of a semicircle?
In a semicircle, the diameter is the straight line. It is also equal to double the radius, and that property allows it to be used when calculating area and circumference.

What is the area outside the triangle if the triangle is inscribed in a semicircle while the side length of triangle is 2underroot2?
Diameter of semicircle = 1 Area of semicircle = Pi/8 Area of triangle = 0.25 Area outside triangle = (Pi/8) - 0.25 = 0.1427 (rounded to 4th decimal).
What is the diameter of a semicircle with a radius of 5 ft?
Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
