The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.

What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
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 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.
What is a semicircle?
a semicircle is half of a circle... so like a circle cut in half, in a straight line. just for some information you may also need in the future: area of a semicircle: multiply the radius by itself and then multiply that by pi (approx. 3.14). divide that by 2. perimeter (circumference) of a semicircle: pi times radius. hope that helps.
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
What is the area of a semicircle whose radius is 5 cm?
50.25cm
What is the area of the semicircle (use 3.14 for and rho)?
That would depend on the radius which has not been given but the area of the semi circle will be (pi*radius squared)/2
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
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 area of a 12 inch semicircle?
Area in square inches = (pi*radius^2)/2
What is the approximate area of a semicircle whose radius is 2Cm?
2pi sq cm
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.
Calculate the area of semicircle with radius 4 meters?
An area of a circle is pi*r2 - so an area of a semicircle is 0.5*pi*r2: 0.5*3.14*42 = 25.13 square meters
What is the approximate circumference of a semicircle with a radius of 30 centimeters?
You can multiply the radius by pi to get the length of the semicircle.
