First we have to find the radius:
pi*radius2 = 120 sq ins
Divide both sides by pi and then square root both sides:
radius = 6.180387232 inches
circumference = 2*pi*radius
circumference = 38.83251825 or 39 inches to the nearest inch.

What is the diameter if circumference is 120 inches?
Diameter of the circle: 120/pi = 38.197 inches rounded
What is the arc length of minor arc 120 degrees?
It will be 1/3 of the circle's circumference
What is the area of a circle that is 120 ft in circumference?
Circumference of circle = 2 x pi x r where r is the radius. So we have here 120 = 2 x pi x r or 60 = pi x r or 60 = 3.1415 x r, Hence r = 60/3.1415 = 19.099 Area of circle is pi x r x r, here it is 3.1415 x 19.099 x 19.099 = 1145.93 square feet
How do you find the arc ABC length 120 degrees 10?
An arc length of 120 degrees is 1/3 of the circumference of a circle
Find the area of a sector in a circle if the radius is 4 cm and the arc has degree 120?
The area of a sector in a circle if the radius is 4 cm and the arc has degree 120 is: 16.76 cm2
What is the diameter if circumference is 120 inches?
Diameter of the circle: 120/pi = 38.197 inches rounded
What is the circumference of a circle if it's area is 120 inches?
This question has already been answered in detail and the answer is 38.83251825 or 39 inches to the nearest foot.
What is the circumference of a circle with a 120 inch diameter?
The ratio of a circle's circumference to its diameter is a constant but irrational (meaning its precise value cannot be fully written out using traditional numbers) number called Pi (π). Pi ~= 3.1415927 Circumference = Pi (3.1415927...) * Diameter (120 inches) ~= 376.991118 inches ~= 377 inches
What is the area of a circle with a circumference of 120 cm?
radius = 120/(2*pi) = 19.09859317 cm area = pi*19.098593172 = 1145.91559 or about 1146 square cm
What is the best estimate of the circumference of a circle with a diameter of 39 inches?
Estimate: 3*40 = 120 inches Actual: pi*39 = 122.5 inches to one decimal place
How large will a circle be using 60 inch line or length?
Circumference will be 120 pi inches, ie 31 feet and very nearly 5 inches
The area of a circle is 120 inches what is its circumference?
A = pi r2r2 = A/pir2(1/2) = (A/pi)1/2r = (120/pi)1/2r ≈ 6 inC = 2 pi rC = (2)(pi)(6 in)C ≈ 37.7 in
If a 120 degree arc is 12mm long what is the circumference of the whole circle?
360 degrees in a circle 120 degrees = 12mm 360 degrees = 36mm Therefore the circumference of the circle is 36mm.
What is the circumference of a circle with a length of an arc 28.61 with a central of 120 what is the circumference?
A central angle of 120 is one third of the circle, so the arc length of 28.61 is one third of the circumference. 28.61 X 3 = 85.83
What is the diameter of a circle with a 120 inch circumference?
Circumference equals pi multiplied by diameter. Therefore 120 (circumference) divided by pi equals diameter. Pi is on your calculator.
If the circumference of a circle is 120 what is the radius?
Divide the circumference by the value of Pi and divide the result by 2 - that will give you your answer.
How many square feet are there in a circle with a circumference of 120 feet?
1145.9
