What is the circumference of a 6 circle?
18.84 inches
The diameter of the circle is 6 inches. We can substitute this given information into our formula and solve for the circumference of the circle. Our answer is 18.84 inches.
What is the area of a 6ft circle?
A = πr2 , where r is the radius of the circle …. Thus, after rounding off the answer to one decimal point, the area of the circle is 113.1 ft2 (answer choice D).
How do you measure a 6 inch circle?
The formula is: circumference = pi times the diameter. For most projects, 3.14 can be used as the value for pi. Rewriting the equation, the circumference = 3.14 X diameter. For example, a circle with a diameter of 6 inches has an approximate circumference of 18.84 inches.
What is the circumference of a circle with diameter?
2 x radius
Circle/Diameter
How many inches around is a 8 inch cake?
8 inch cakes can be sensibly served to 14 people cutting each slice at about 2 1⁄4 inches across the back. 2 1⁄4 inches is about the length of the spoon part of a tablespoon. 8 inch cakes can also be cut event style.
What is the formula for finding the diameter of a circle?
If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter. This goes back to manipulating the formula for finding the area of a circle, A = πr 2, to get the diameter. You can transform this into r = √(A/π) cm.
What is the area of a six inch diameter circle?
2 Answers The diameter is the distance across the circle, so a 6 inch diameter would be 6 inches from one side across the middle to the other side. Most ladies hands, from heal to tip of middle finger, is 6-7 inches so you can use that as a visual. Pinch your finger together with your thumb to form a circle and this is approximately 6 inches around.
What is the area of a circle with a radius of 6?
Given that the area, A, of a circle is defined by the following formula: A = πr 2 , where r is the radius of the circle …. ….then the area of a circle with a radius of 6 ft is as follows: Thus, after rounding off the answer to one decimal point, the area of the circle is 113.1 ft 2 (answer choice D).
How do you find the area of a circle equation?
The formula for the area of a circle is π x radius 2, but the diameter of the circle is d = 2 x r 2, so another way to write it is π x (diameter / 2) 2.
