find the radius of a circle with the circumference of 273 inches.
C = 2 r π
r = C / 2π = 273 / 2 ∙ 3.14159 = 273 / 6.28318 = 43.45 in
since radius is half of the circumference, you would be having to divide 273 by 2 which equals 136.5
Sophia, where did you learn geometry?
To find the radius of a circle with a given circumference, you can use the formula:
Circumference = 2 * pi * radius
Given that the circumference of the circle is 273 inches, we can substitute this value into the formula and rearrange it to solve for the radius.
273 = 2 * pi * radius
To isolate the radius, divide both sides of the equation by 2 * pi:
radius = 273 / (2 * pi)
Now, let's calculate the value of the radius using a calculator.
- Convert the value of pi to decimal (approximately 3.14).
- Plug in the values and perform the calculation:
radius = 273 / (2 * 3.14)
radius ≈ 43.5457
Therefore, the radius of the circle with a circumference of 273 inches is approximately 43.55 inches.
