What is the area of a circle that has a 25 inch diameter?
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
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
If the area of a circle is 312 sq ft what is the diameter?
(1248/pi) ft ^ (1/2) = 19.9 ft
How many sq feet in a 21 foot diameter circle?
Area of any circle = (pi) x (radius)2Radius = 1/2 of the diameter.With this information, you can now find the area of any circle,including that one, on your own.
What is the are of a yd circle?
The area of a circle with a diameter of 1 yard is approximately 0.785 square yards.

If the area of a circle is 312 sq ft what is the diameter?
(1248/pi) ft ^ (1/2) = 19.9 ft
What is the area of a circle if the diameter is 37in.?
area = pir2 r = 1/2 X diameter pi = 3.1416 area = 3.1416 X (37/2)2 = 1075 sq. in.
What is the area of a circle with a diameter of 11 feet?
Area = (1/4)*Ï€*d2 where d is the diameter. So area = pi*121/4 = 95.033 sq ft (to 3 dp)
Which area is bigger a circle with a diameter of 10 feet or a triangle with an area of 100 sq ft?
Use the standard formula to calculate the area of the circle, then you can compare with the area given for the triangle. Note 1: The formula for a circle is: area = pi x radius squared Note 2: The radius is half the diameter
How many square feet is 24 inch circle?
a 24 inch circle is a 2 ft diameter circle, or a 1 ft radius circle. the area of a circle is pi * r squared, so 1 ft squared is 1 sq ft. Times pi (=3.14159) is 3.14159 sq ft
Area of circle with diameter?
Area of a circle = (1/4) x (pi) x (square of the diameter)
How many sq feet in a 21 foot diameter circle?
Area of any circle = (pi) x (radius)2Radius = 1/2 of the diameter.With this information, you can now find the area of any circle,including that one, on your own.
The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?
The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
What is the are of a yd circle?
The area of a circle with a diameter of 1 yard is approximately 0.785 square yards.
The diameter of a circle 12mm what is the area?
A = Pi x R² (Pi = 3.1416, R² = 1/2 diameter multiplied by itself) 3.1416 x 36 113.0976 sq mm
