what- a pie tin has a circumference of about 25 inches.Which is the best approximation for the radius of the tin?
The pie tin is circular.
So apply the circular equation/
C = 2 pi r
Algebraically rearrange
r = C / ( 2 pi)
r = 25/(2 x 3.14)
C = 25/ 6.28
C = 3.9808.... incges ~ 4 inches,.

If the circumference of a circle is 44 centimeters what is the best estimate for the length of the radius of the circle?
It is very close to 7 cm. Circumference = pi (2r) c = 6.2832 r = 44 44/6.2832 = 7.003

How do you find the circumference and area of a circle?
-- If you know either the area or the circumference of the circle, you can calculate the other one. -- If you don't know either the area or the circumference, then you have to either measure the circle's diameter, or ask around and try to find someone who already knows what the length of the diameter is. -- Once you have the diameter, take 1/2 of it. That's called the circle's "radius". -- The area of the circle is (pi) x (radius)2 -- The circumference of the circle is (2 pi) x (radius) or (pi) x (diameter). (Pi) is a number that can never be exactly written down, so the best you can do is use some number that's close. The closer your number is to (pi), the closer your answer will be to the truth, but it can never be exactly and perfectly correct. (Pi) is approximately 3.1415926 . But the easiest and most practical way to work with it is to use 22/7 for it. If you do that, then your answers are only about 0.04 percent wrong, and that's actually pretty darn good.
What happens to the area of a circle if the circumference is doubled?
If the circumference of a circle is doubled, the area will be four times bigger. It's like having a square with one metre sides. If we double the length of sides, that is - two metre long sides. the length around will be eight instead if four metres. The area will not be doubled from one square metre to two square meters. It will be four square metres instead. Lengths only grow in one direction so doubling is doubling, but areas grow in two directions - length and width at the same time. Therefore, areas grow and grow, doubling this way and doubling that way, so the doubling is doubled making it four times. Trebling would be trebled making a three times length increase into a nine times area increase.

What is the best approximation for the circle with a diameter of 13 meters Use 3.14 to approximate pi.?
To find the best approximation for the circle with a diameter of 13 meters, we first calculate its radius, which is half the diameter, giving us a radius of 6.5 meters. The circumference of the circle can be calculated using the formula (C = \pi \times d), where (d) is the diameter. Using 3.14 for (\pi), the circumference is (C = 3.14 \times 13 \approx 40.82) meters. The area can be calculated using the formula (A = \pi \times r^2), resulting in (A \approx 3.14 \times (6.5)^2 \approx 132.65) square meters.

If the circumference of a circle is 25.12 centimeters what is the best estimate for the length of the radius?
The circumference of a circle with a radius r is P=2*pi*r so: r=P/(2*pi)=25.12/(2*pi)=3.9979721704684108345143601359176~4 cm

10 inches
What is the best estimate of the circumference of a circle if the radius is 15 inches?
Use Circumference = 2 x radius x Pi Pi is 3.14159 appx. Therefore the circumference of your circle is 2 X 15 X 3.14159 inches or 94.25 inches or 7 feet 10 and 1 quarter inches
What is the circumference of a circle with a diameter of 5?
The formula for a circumference is 2 times Pi times Radius. A diameter is twice the Radius, so the circumference is Diameter times Pi. 5 times Pi (3.14159) is approximately 15.70795. Pi has an endless number of digits to the right of the decimal point, so the best we can do is approximate.
