If the radius of a circle is 7 inches long what is the length of the diameter of the circle?
14 inches.
Find the area of a circle with a diameter of 5 inches long?
pi x 2.5 squared because 2.5 is the radius. the radius OS half the diameter. the formula for area of a circle is pi x r squared. pi is 3.141593
How do you find the perimeter of a circle with just the diameter?
the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long
Mark has a piece of string 12 inches long he shapes string into rectangle that encloses an area of 5 square inches Can Mark enclose a greater area with the same string If sowhat is the area?
If Mark makes a circle, that circle would have a circumference of 12 inches. The formula for circumference is pi times diameter, so the circumference divided by pi will give you the diameter of 3.82 inches. Divide this by 2 to get the radius of 1.91 inches. Area of a circle is pi times the radius squared. 1.91 squared is 3.6481. Multiply this by pi to get 11.46 square inches of area inside the circle. A circle is always the most efficient use of space possible given a fixed perimeter. If Mark makes a square with equal sides where all sides are 3 inches, the area would be 9 square inches. 3 X 3 = 9
How long does a piece of string need to be to make a circle that is 32 inches in diameter?
pi*32 = 100.53 inches (approx)
What is the area of a circle if it has a diameter which is 16 inches long?
The area is 201.1 square inches.
If the radius of a circle is 7 inches long what is the length of the diameter of the circle?
14 inches.
What is the area of a circle if it has a diameter of 17 inches long?

The diameter of a circle is 19 inches. If the diameter is extended 5 inches beyond the circle to point C, how long is the tangent segment from point C to the circle?
6.283 inches
If a radius is 15 inches long, how long is a diameter?
The radius of a circle is half the diameter, thus your measurement is 30 inches
What is the area of a circle if it has a diameter which is 13 feet long?
The area of a circle, if it has a diameter of 13 feet, is: 132.7 square feet.
If the diameter of a circle is 12 inches how long is the radius?
Diameter of a circle is defined as twice the radius. So if diameter is 12, the radius is 6.
Radius of circle is 16 inches how long is diameter?
32"
Find the area of a circle with a diameter of 5 inches long?
pi x 2.5 squared because 2.5 is the radius. the radius OS half the diameter. the formula for area of a circle is pi x r squared. pi is 3.141593
What is the area of a circle if it has a diameter which is 13 inches long?
The area of a circle is pi(r)^2 (Pi times r squared) r = (1/2) dSo if the diameter is 13, the radius is 6.5Now use the equation:A=pi(6.5)^2A=pi(42.25)A=132.73 square inches.
The diameter of a circle measures 1 foot 4 inches How long is the raduis of the circle?
The radius (not raduis) is 8 inches.
How do you find the perimeter of a circle with just the diameter?
the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long
