What is the area of a circle that has a diameter of four feet?
The area of a circle that has a diameter of four feet is: about 12.57 square feet.
What is the raduis of a circle that is inside a square with an area of 400 cm?
Assuming the circle is tangent to the sides of the square, then the edges of the circle meet the square at the midpoint on each of the four sides. So the diameter of the circle is the same as the length of a side of the square. So all you need to do is find the length from the total area by taking the square root of the area (since A = s2), which gives you the diameter, then halve it to get the radius.
What is the area of a circle if the diameter is four an three fourths?
The area of a circle with a diameter of 4.75 is: 17.72 square units.
How do you find the circumference of a quarter circle?
easy pi 3.141592654 or 3.14 times the diameter then divide by four first you find the entire circumference then cut into halves or quarters
How do you find the radius of a circle given the diameter?
The radius of a circle is half of the diameter! So, if the diameter was four inches, the radius would be two inches!
What is the circumference of a circle with a diameter of four?
If a circle has a diameter of 4 bananas, it's circumference is 12.564 bananas
What is the diameter of a circle with a 12 meter circumference?
Diameter of circle: 12/pi = 3.8197 meters to four decimal places
What is half of a quarter of a circle called?
A half of a quarter of a circle is 1/8 of a circle. There are four pieces making 1/4. If you split all of them into halves you have eighths.
What would be a the radius of a circle with a diameter of 8 inches?
four inches
If the circumference of a circle is twenty four meters what would the diameter?
If the circumference of a circle is 24 meters the diameter will be about 7.639 meters. (d = C divided by Pi).
Square of diameter?
The square of the diameter of a circle is equal to four times the square of the radius of the circle. This relationship arises from the formula for the diameter of a circle, which is two times the radius, and squaring both sides of this equation.
What happens to the area of the circle when the diameter is doubled?
As the area of a circle A equals pi times the radius squared, and doubling the diameter means multiplying the radius by four, the area is multiplied by 16 when you double the diameter.
