Answer:
60π
Step-by-step explanation:
If the circle has radius of 30 units, substitute r=30 into the formula C = 2πr.
C = 2π(30)
C = 60π
Can you show the multiple choice one
Answer:
C
Step-by-step explanation:
So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing
(you have to divide by 2 because it's only have a circle).
The radius is half of 15, so 15 / 2 = 7.5. This would be:




The last step is to add 450 + 88.3125 = about 538.3 m^2
She would be able to download 49 at this rate.
Because 5/35 =7/n which would then =245/5 which equals 49
I believe the answer to your question is A
