What is the area of the circle if the diameter is 6 m?
A: 9m
B: 18 m
C: 27 m
D: 108 m
I think the answer is B because if times the diameter by 3 then you get 18.
The answer isn't 18. After looking at the material Ms Sue posted for the previous question, rework this one with that information.
Yes, I reworked it and I got 27 m.
I did this problem and I got 28.27...hm.. is my calculator incorrect?
I don't think so since I went to the site and the area of a circle is pi r^2
r= 3 and they have the same problem on the site that was given by Ms.Sue!... o.O;;
Reading below, if you use 3 instead of 3.14..etc.
then you get 27 so that is correct. =D
i need help
To find the area of a circle, you need to use the formula A = πr², where A represents the area and r represents the radius of the circle. The radius can be calculated by dividing the diameter by 2.
In this case, the diameter is given as 6 m. To find the radius, divide the diameter by 2: 6 m ÷ 2 = 3 m. Now we have the radius.
To find the area, substitute the radius into the formula: A = π(3 m)².
To calculate the area, square the radius: (3 m)² = 9 m².
Finally, multiply the squared radius by π (approximately 3.14): A = 9 m² × 3.14 ≈ 28.26 m².
None of the options provided (A, B, C, or D) match the actual area of the circle. Therefore, the correct answer is not present among the given options.
