B and C make sense to me.
Answer:
10
Step-by-step explanation:
1 out of 50 got it, so 500/50=10
Answer: B
Step-by-step explanation:
The area of a circle is pi*radius^2. But only a diameter is given, so in order to find the radius, you must divide the diameter by 2:
3.6/2 = 1.8
Now, you can plug the radius, 1.8, into the equation pi*radius^2 (
):
= about 10.18
Lastly, you must divide the area 10.18 by 2 because you are looking for only half the area.
10.18/2 = 5.09
C
The word “increased” means to add, so C would be the correct answer. Hope this helps!
