The area of the circle with a 3 inch diameter is pi*1.5^2 = 7.069 square inches rounded
Area = A
radius of circle = r
pi = 3.14159265
A = pi x r^2
A = 3.14159265 * (1.5) ^ 2
A = 3.14159265 *2.25
A = 7.06858

What is the area of a circle if the diameter 28.9m?
Area = pi*14.452 = 655.972 square m to 3 dp
If the diameter of a circle is 6 feet what is the area of the circle in square feet?
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
What is the area for a small 20ft Circle?
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)
How do you find the area of a circle if the circumference is 10?
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.
How do you use pi to find a circle's dimensions?
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 .
How many square inches are in the area of 3 inch diameter circle?
The area of a 3-inch diameter circle is about 7.068 square inches.
What is the area of a circle with a one inch diameter?
Area = pi * diameter * diameter /4 = 3.14 * 1 *1 /4 = approx = 3/4 of square inch
What is the surface area of an 11 inch diameter circle?
Area of the circle = pi*5.52 = 95.033 square inches to 3 decimal places
What is the area of a 19.6 inch diameter circle?
Area = pi*9.82 = 301.719 square inches to 3 dp
How calculate area circle?
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
What is the area of 6 inch diameter circle?
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
Area of a circle that has diameter of 3 cm?
The area of a circle that has diameter of 3 cm is: 7.069 cm2
What is the radius of a circle with a 6inches diameter?
The radius of a circle is half the diameter, so the radius of a 6 inch diameter circle is 3 in.
What is the area of 11 inch diameter circle?
It is: pi*5.52 = 95.033 square inches to 3 decimal places
What is the area of a three quarter inch diameter circle?
Area = pi*3/82 = 0.4417864669 or 0.442 correct to three decimal places
What is the radius of a 3 inch circle?
If "3 inches" refers to the circle's diameter, then the radius is one-half of that.
