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 diameter in geometry?
diameter refers to the area across a circle through its center. it is the longest chord possible for any given circle.
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
How do you find the area of a circle when given diameter?
A = pi x d2 / 4
How do you find the diameter when given the area?
depends greatly on the thing you are working with. assuming a circle with area A the diameter is 2*sqrt(A*pi) since A =r*r*pi and diameter=2*r
If the area of a circle is given as 67cm squared find the diameter and then circumference of this circle?
If the area of a circle is given as 67cm squared, the diameter is 9.236 cm and the circumference is 29.02 cm
What is the area of a circle that has a 10 inch diameter?
The area of a circle is A = pi times diameter² / 4. Given diameter d = 10 inches. Area A = 78.5398 inches².
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.
How do you find the area of a circle when the radius is unknown?
By using the other information supplied about the circle to calculate either its radius (from which its area can be calculated) or its area (if the circle is similar to another with a given area and some ratio between the two circle is given):If the diameter is given: radius = diameter ÷ 2If the circumference is given: radius = circumference ÷ 2πIf the circle is similar to another circle which has a given area, and the length ratio is given; square the length ratio to get the area ratio and apply to the given area.
How do you find area of a circle when diameter is given?
TTr2 [Pi r squared] finds the area of the circle. TT x d [Pi x diameter] finds the circumference of a circle]
What is diameter in geometry?
diameter refers to the area across a circle through its center. it is the longest chord possible for any given circle.
How do you find the area of a circle if the diameter is given?
multiple the diameter by 2 to get the radius, then use your equation and go from there
How do you find the area of a circle when given diameter?
A = pi x d2 / 4
How do you find the diameter when given the area?
depends greatly on the thing you are working with. assuming a circle with area A the diameter is 2*sqrt(A*pi) since A =r*r*pi and diameter=2*r
What is the formula for the area of the circle given the diameter?
in place of r (radius) write d/2 where d is diameter
Area of a circle with a 12 inch circumference?
The circumference of a circle is given by Circumference = pi x diameter. The area of a circle is given by Area = pi/4 x diameter2. Thus for a circle with circumference c = 12 in. The area will equal a = 11.459 in2.
How do you find the area of the circle if diameter is given?
Area = pi*r2 where r is the radius. Since r = diameter/2, then area = pi*d2/4
