Sorry for posting again-- But I need help with this question too
2. A sphere has a diameter of 28 millimeters. What is the circumference of the great circle?
A. 43.96 millimeters
B. 87.92 millimeters**
C. 125.84 millimeters
D. 615.44 millimeters
I think I did something wrong, so can someone check
Yes, it would be B.
C= π x r
radius would be 28/2 = 14
2π x 14 = 87.92 millimeters
Thank you!
To find the circumference of a circle, you can use the formula:
Circumference = π * diameter
Given that the diameter of the sphere is 28 millimeters, we can substitute this value into the formula:
Circumference = π * 28
To find the value of π (pi), we use an approximation of 3.14. Substituting this value, we can calculate the circumference:
Circumference = 3.14 * 28
Calculating this multiplication, we get:
Circumference ≈ 87.92 millimeters
Therefore, the correct answer is B. 87.92 millimeters.
