Using 3.14 as Pi the area of circle is: 3.14
What else can I help you with?
If the radius of a circle is 2cm what is the diameter?
Diameter of circle = 2 * Radius of the circle.
How do I figure the area of a circle by diameter?
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
What is the area of a circle if the diameter is 9.75 if pi is 3.14?
The area equals pi times the radius squared. The radius is half the diameter. The area of the circle = (9.75/2)2(3.14) = 74.6240625 or about 74.6 units squared.
What is the area of a circle if xy equals 5.4 mm?
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
What is the area of a circle that has a diameter of 2 feet?
The area of a circle with a diameter of 2 feet is 3.14159 square feet, approximately.
What is the square foot of a circle with a diameter of 3 feet?
Area of a Circle: A = (pi) * r ^ 2 (Area equals Pi Times the radius Squared) R = 3/2 (Diameter = 3, Radius = 1/2 of the Diameter) A = 3.1415 * (3/2)^2 A = 3.1415 * 2.25 A = ~7.068 Square Feet
Area of a circle with 2 inch diameter?
In a circle, Area = pi times radius squared: A = (pi)(r^2) Since the diameter equals 2 inches, the radius is one inch: A = (pi)(1^2) A = pi = 3.14 inches squared
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 area of a 28 cm circle using pi?
The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2
How do you get a area from the diameter?
The equation for the surface area of a circle is Pi times the radius squared. Pi x r^2 = Area of a circle The radius is 1/2 the diameter therefore if d is the diameter; Pi x (d/2)^2 = Area of a circle
What is the area of a circle with a diameter of 14.4?
AREA= Pi x (1/2 diameter)^2
What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
