Radius of circle is 16 inches how long is diameter?
32"
What is the diameter of a circle that is 20 inches long?
The diameter is the same as the length, so it is 20 inches. If you meant to say that the circumference was 20 inches, then divide by pi, which is 3.1416 20 / 3.1416 = 6.4 inches
What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
Is the diameter of a circle bigger or smaller then the radius?
The diameter is twice as long as the radius. d = 2r The diameter is basically a line through the center of a circle while a radius is from the center to the circumference of a circle.
If you measured both circumference and diameter in inches instead of in centimeter would it affect the value of pi?
No. "pi" is the 'ratio' of circumference to diameter of a circle. It doesn't care what the unit is,just as long as both are measured in the same unit.
What is the area of a circle with a diameter that is 20 inches long?
using area = pi *r^2 we get: 314.1592654
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?
8.5 x 8.5 x (355/113)
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.
Radius of circle is 16 inches how long is diameter?
32"
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.
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
