I think C. Thank you
I agree. C.
Yep... C
To estimate the sum of a circle with a radius of 27m, you need to calculate the circumference of the circle.
The formula for calculating the circumference of a circle is: circumference = 2 * π * radius
Given that the radius is 27m and using the value of π as 22/7, we can calculate the circumference as follows:
circumference = 2 * (22/7) * 27
= 2 * 22 * 27 / 7
= 1188 / 7
= 169.71428571428572 m
Therefore, the sum of the circle, which is equal to the circumference, is approximately 169.71 meters.
Since none of the provided answer choices match this value, none of the options A, B, C, or D are correct.
To estimate the sum of a circle with a radius of 27 meters, you need to find the circumference of the circle using the formula: circumference = 2 * π * radius.
Given that you should use π as 22/7, the calculation would be:
circumference = 2 * (22/7) * 27
Simplifying this calculation:
circumference = (44/7) * 27
circumference = (44 * 27)/7
circumference ≈ 304.2857 meters
Now, to estimate the sum of the circle, you need to multiply the circumference by the radius. So:
sum = circumference * radius
sum ≈ 304.2857 * 27
sum ≈ 8219.9999 square meters
Rounding this to the nearest whole number, the estimated sum of the circle is approximately 8220 square meters.
Among the given options, option C (2291 square meters) is different from the calculated estimate. Therefore, C cannot be the correct answer.
Instead, the closest estimate to the calculated value is option D (5253 square meters), which is closer to the estimated sum of 8220 square meters.
