Area = pi*14.452 = 655.972 square m to 3 dp
The area of a 6-foot diameter circle is about 28.274 square feet. A = pi r2 (r = 6/2 = 3) A = (3.1416)(32) = approximately 28.274
The area is the same as that of a big 20 ft circle. Assuming the 20 ft refers to the diameter of the circle, its area is 314.159 sq ft (to 3 dp)
We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.
Pi is defined as the ratio of the circumference of a circle to the diameter of the circle.Therefore, if you measure the diameter of the circle (call it 'D') then the circumference of the circle is pi times D.To find the area of the circle use the formula Area = pi* D2 /4 .Going one step further, to a sphere, if you measure the radius of the sphere (call it R, where R is half the diameter D), then:1) The surface area of the sphere is Area = 4 * pi * R2 .2) The volume of the sphere is Volume = (4/3) * pi * R3 .
The area of a 3-inch diameter circle is about 7.068 square inches.
Area = pi * diameter * diameter /4 = 3.14 * 1 *1 /4 = approx = 3/4 of square inch
Area of the circle = pi*5.52 = 95.033 square inches to 3 decimal places
Area = pi*9.82 = 301.719 square inches to 3 dp
The formula for finding the area of a circle is pi * r², where pi = 3.14; * = multiply; r = 1/2 of the diameter; and ² = squared (multiplied by itself). An example of how to calculate the area of a circle with a 6 inch diameter (3 inch radius): a = Pi * r² a = 3.14 * 3² a = 3.14 * 9 a = 28.26
The formula for calculating the area of a circle is:r²πSo, the area of a circle with a diameter of 6 inches (with a radius of 3 inches) is:3²π = 9π ≈ 28.2743 in²
The area of a circle that has diameter of 3 cm is: 7.069 cm2
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
It is: pi*5.52 = 95.033 square inches to 3 decimal places
Area = pi*3/82 = 0.4417864669 or 0.442 correct to three decimal places
If "3 inches" refers to the circle's diameter, then the radius is one-half of that.
