I have these same questions but the way i solved them i did
A: 1/3 x 3.14 x 2*2 x 8 = 32/3 = 2000 divided by 32 = 63 scoops
The formula is 1/3 x 3.14 x r*2 x h
B: 1/3 x 3.14 x 8*2 x 8 = 128/3 = 2000 divided by 128 = 16 scoops
After the new test, she now has taken 8 tests.
Set it up just like when finding the average:
(87+79)/8
Solve for the new test average
-2 and -4
Hope this helps!
