A circle's radius is always 1/2 of the circle's diameter, so the radius of a circle of 5-inch diameter is 2-1/2 inches.
Assuming a diameter of 5 inches.The area of this circle is: 19.63
15 ' 8 1/2" The length of the circumference of a 5' diameter circle is 5*pi feet or about 15.7' but as the diameter was only given with one significant figure the answer may only have one significant figure of accuracy so2 times 101 feet
It works out as the square root of 5 or about 2.236 to three decimal places
The diameter of the circle will also be the triangle's hypotenuse so use Pythagoras theorem to find the hypotenuse's length and half the length which will result as a radius of 5 cm.
If the radius is 5 feet then the diameter is 10 feet
A circle's radius is always 1/2 of the circle's diameter, so the radius of a circle of 5-inch diameter is 2-1/2 inches.
The radius is 1/2 of the diameter. A diameter of 10 has a radius of 5.
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
If a circle has a diameter of 5 the circumference is: 31.4
Assuming a diameter of 5 inches.The area of this circle is: 19.63

The diameter of the circle will also be the triangle's hypotenuse so use Pythagoras theorem to find the hypotenuse's length and half the length which will result as a radius of 5 cm.
The area of a circle with a 5-inch diameter is: 19.63 square inches.
The equation for determining the circumference of a circle is circumference = pi x diameter. So if the diameter is 5, then the circumference is pi * 5 = 15.71
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
