Using the formula C = 2πr, find the circumference of a circle with diameter of 28 inches. Round your answer to the nearest inch. A. 88 in. B. 44 in. C. 28 in. D. 56 in.

Answers

Answer 1
Answer: the formula given to us relates circumference with radius but we are given diameter instead. good thing we know that diameter is twice the length of radius so if diameter=28, the radius=14. therefore, using our formula, we can find the circumference:
C = 2(pi)(14)
C = 87.96
and this answer is close to 88 so the answer is A

let me know if you have any questions!!!
Answer 2
Answer: Hi there! C=πd=π*28=87.96459, 87.96 rounded to the nearest tenth would be 88. Therefore, your answer is A. 88 in

Round 44.8 to the nearest whole number

Answers

55 is the nearest whole number

Answer:

45 is the nearest whole number.

Step-by-step explanation:

You look at the first decimal when rounding to the nearest whole number.

4 or less let it rest

Example: 36.2

2 is less than 4 so you let it rest and the nearest whole number would be 36.

5 or more raise the score

Example: 36.6

6 is 5 or more so you raise the score and the nearest whole number would be 37.
