Final answer:
To find the circumference of a circle with an area of approximately 113 square centimeters, use the formula A = πr² to solve for the radius, then use C = 2πr to find the circumference. The calculations suggest a circumference of approximately 37.68 cm, which does not match the provided options.
Step-by-step explanation:
To find the circumference of a circle when given the area, you can use the relationship between the area and the radius, and then find the circumference using the radius. The area of a circle (A) is given by πr², and the circumference (C) is given by 2πr. If we know the area is approximately 113 square centimeters, we first solve for the radius using the area formula:
A = πr².
Substituting 113 for A and 3.14 for π, we get:
113 = 3.14r²
Next, we solve for r²:
r² = 113 / 3.14
r² ≈ 36
Then, we take the square root to find r:
r ≈ 6 cm.
Now, we use the radius to find the circumference:
C = 2πr
C ≈ 2 × 3.14 × 6
C ≈ 37.68 cm.
Since the options given do not match this result, it appears there is a mistake in either the calculation or the options provided. We should revisit the calculations or verify the options with additional sources.
