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 width of a rectangle with area of 72 and length of 12?
You use the equation Area = width x length. And solve for the width. You solve it by dividing both sides by the length to get.. Area/length = width
What is the area of a semicircle whose radius is 5 cm?
50.25cm
How do you find the area of a triangle given the height?
You don't have enough information. But if you have the base and the area, you can solve the equation for the area of the triangle for the height.
What are some ways to solve an equation?
solve it
What is the area of a semicircle when the radius is 21?
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 the graphic equation of a semicircle?
5
What is the equation for a semicircle?
x2+y2=r2, y>=0
What is the area of the semicircle if the length of the arc of a semicircle is 10 and pi feet?
It is 27.49 units.
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 formula to find a semicircle?
I think that you are asking for the equation of a semi-circle. If you have a circle with radius r and centered at (0,0), its equation is x^2 + y^2 = r^2 The upper semicircle has the equation: y = sqrt(r^2 - x^2) with -r ≤ x ≤ r <------------------ Answer By using the square root I only get points where the y coordinate is positive and thus all points are restricted to the upper semicircle. The area is ((π * r^2) / 2) The perimeter is (π * r)
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
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).
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 width of a rectangle with area of 72 and length of 12?
You use the equation Area = width x length. And solve for the width. You solve it by dividing both sides by the length to get.. Area/length = width
Can you solve for a variable in an equation?
Sure. You can always 'solve for' a variable, and if it happens to be the only variable in the equation, than that's how you solve the equation.
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
