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.
What is the area of a circle with a diameter of 6 in?
The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)
What is the circumference of a circle with a diameter of 3 inches?
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
How do you find the radius squared?
Radius squared is half of the diameter multiplied by itself. Example: diameter is 6 inches, radius is 3 inches (half of diameter), radius squared is 9 inches (radius multiplied by itself 3 x 3 = 9).
What is the diameter of a circle if the radius is 3?
the diameter would be 6.
If a circle has a radius of 3 inches what is the circle's diameter?
6 inches. always multiply radius by 2 to get diameter
What is the radius in inches of a circle if the diameter is 3 inches?
Radius is merely..., diameter/2 3 inches/2 = 1.5 inches in radius ==============
What is the diameter of a circle with the radius of 3 inches?
7 inches, radius+1in=diameter. Always.
If a circle has a radius of 3 inches what is its diameter?
6
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.
What is the circumference of circle with radius of 3 inches and diameter of 10 in ches?
A circle with radius of 3 inches doesn't have a diameter of 10 inches. If the radius is 3, then the diameter is 6, and the circumference is (6 pi) = 18.85 . (rounded) If the diameter is 10, then the radius is 5, and the circumference is (10 pi) = 31.42 . (rounded) The diameter is always double the radius, and the radius is always half of the diameter.
What is the radius of a 6 feet 6 inches circle?
If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches
What is a circle's diameter when its length is 3 inches greater than its radius and has a circumference of 18.849 inches?
6 inches because the diameter is twice the radius 3+3 = 6 circumference = pi*6 = 18.849 inches
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.
If a circle has a radius that measures 3 inches what would the diameter be?
Well the radius is half the diameter so it would be 3 + 3 which is 6...therefore D = 6
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
If the circumference of a circle is 3 pi then what is the radius and the diameter?
The radius of the circle is 1.5 units and the diameter is 3 units.
