Adding a negative number is the same as subtracting a positive number. So 2315.5 - 3166.75 = -851.25
V = (1/4)(π* d² * h)
<span>V = (1/4)(π * 10² * 12) </span>
<span>V = (1/4)(1200π) </span>
<span>V = 300π </span>
<span>[ V ≈ 942 cubic units . . . . . to 3 s.f. ] </span>
<span>V ≈ 942 cubic units

Answer:
Winnie needs to buy 6 slices of Coffee cake.
Step-by-step explanation:
12 * 5= $60 (chocolate cake)
120 - 60= 60

60/ $10= 6 slices of coffee cake.
1/25 of a minute is 2,4 secs.
1/5 = 2,4s
5/5 = 12 secs
